STDL: Week 16 - Broncos at Bills

Let's take a quick pre-game look at how the Broncos and Bills match up:

STDL: QB stats through 15 weeks

Let's see how Tim Tebow's offensive numbers look after nine starts as the Broncos starting QB. Prior to the New England game, Tebow was 20th in the league in Adjusted Net Yards per Touch and 33rd in Net Yards per Touch, out of the 40 passers who had attempted 100 or more passes. While there are now 43 QBs who've thrown over 100 passes, we'll constrain the list to the top 40 players in terms of attempts:

STDL: Week 15 - Broncos vs Patriots

Interesting matchup today, right? Have you ever seen so much talk about a regular-season game featuring an eight-point spread (the third-biggest one behind Packers/Chiefs and Saints/Vikings)? It's pretty bizarre, but that's the power of Tim Tebow. He's all anyone ever wants to talk or read about (just ask Skip Bayless about his show's ratings), except of course for when the author/commentator's viewpoint doesn't match that of the readers/viewers/listeners.

This is the animal we're dealing with. Anyway, big betting line or not, this is an exciting day to be a Broncos fan, because we get to see how our team measures up against NFL royalty (if not the far-from-perfect class of the conference). Let's see how the two teams match up.

STDL: QB stats through 14 weeks

Tim Tebow attempted 40 passes last week, so he finally qualifies to be ranked in NFL QB rate stats. In terms of traditional QB rating, Tebow sits at 14th among 32 qualifiers at 83.9, and in terms of PFR's NY/A and ANY/A he ranks 29th and 18th, respectively, out of 32 quarterbacks.

Those rankings aren't so bad, especially relative to the criticism lobbed at Tebow's play from folks like, well, this guy. Of course, the whole point of doing this is to see how much Tebow's running adds to his offensive contribution to the Broncos as compared to other QBs who run less, or not as well. Let's see how the numbers have changed since the first and second weeks we've done this.

STDL: Week 14 - Broncos vs Bears

On Thursday we covered Tim Tebow's stats through Week 13; today let's examine the full team's numbers and how they match up with the Bears. Of course, Chicago's offense will be without Jay Cutler and Matt Forte, who have been responsible for 82.1% of the Bears' net offensive yardage but just 57% of their touchdowns. Chicago has also scored a combined six touchdowns on interceptions and Devin Hester's punt and kick returns. Marion Barber (five rushing scores) and Cutler's backup Caleb Hanie (two TD passes) round out their scoring. The absence of Cutler and Forte is sure to loom large tomorrow, but keep in mind that the following numbers were achieved largely on their broad shoulders.

STDL: QB stats Week 14

So, it turns out that Tim Tebow's 15 pass attempts on Sunday weren't enough for his 2011 stats to qualify for rate stats leaderboards, but that won't stop us from updating the numbers. Last week, Tim ranked 19th in ANY/A and 36th in NY/A out of 39 QBs with 100 or more pass attempts. Incidentally, Tyler Palko became the 40th passer to cross that threshold with his 30 attempts against Denver's upcoming opponent.

As one might expect, Tim's sparkling second-half performance in Minnesota served to move him significantly higher in both categories. This speaks to two factors: one, we're still looking at a relatively small sample size which can be easily influenced by a single game; two, his results Sunday were that much better than his prior ones.

STDL: Week 13 - Broncos at Vikings, plus Tebow stats

We're going to change things up a little bit with Week 13's STDL. As I mentioned last week, I'd been thinking of switching the passing numbers here to NY/A (Net Yards per Attempt) from ANY/A (Adjusted Net Yards per Attempt) since NY/A is better at predicting future results, which is the whole point of this column. NY/A adds sack data to plain old YPA (Yards per Attempt), while ANY/A adds the weight of touchdowns and interceptions to the mix. Why is NY/A more predictive, while ANY/A is more retrodictive (better at explaining why something already happened, rather than what's likely to happen next)?

Touchdowns and interceptions are more random than YPA. Not random, mind you, just more random than YPA - in other words, if your offense is effective at moving the ball down the field, it's likely to score more than an offense that doesn't move the ball well. Naturally, the 2008 Broncos would stand as a stark exception (2nd in Yards per Play, 16th in Points). Of course, this means I need to reconsider whether to keep touchdowns in with the rushing data. That could be next week's tweak...

Plus, we'll take a look at how Tim Tebow stands in relation to the other QBs in the league via NY/A and ANY/A data, but with rushing stats baked in! As always, there'll be something in it for Tebowmaniacs and Tebow Skeptics alike.

Kerry Byrne can cherry-pick with the best of them

Yesterday we again decried ESPN's attempts to paint their own Total QBR as a revolutionary passing metric. Another day, another gross instance of statistical malfeasance, this time delivered by CHFF's Kerry Byrne in a column for SI. It's pretty bad, quite frankly - virtually a page out of the playbook for how to misinterpret and overstate stats and their meaning.

The spirit of what Byrne and CHFF are trying to do (factor rushing into a QB rating) is excellent, and in full disclosure it's something I've also been working on since last year myself. Yet, the manner in which Byrne is presenting the data for Tebow's 2011 starts is completely self-serving and ignores some crucial context. Let's examine some of the more glaring fallacies of Byrne's column:

STDL: Week 12 - Broncos at Chargers

The Broncos are undoubtedly in the thick of things in the AFC West, and a victory tomorrow could all but end the Chargers' chances to take back the division they had ruled for five out of six years prior to last year's stumble. San Diego is reeling, having lost five straight games (the first four by a single score) and turning the ball over an astonishing 14 times during that stretch. Of course, the Broncos are on the upswing, have won four of their last five, and they've given it away just once in three games. Just how likely is Denver to pull of their (previously unimaginable) third road divisional win in four weeks' time? Let's check out the Stats That Don't Lie to find out:

STDL: Week 11 - Broncos vs Jets

The Broncos and Jets open Week 11 tonight, and the rest of the country will get its first look at Tim Tebow as a starting NFL QB. What will they get? Three yards and a cloud of dust from both teams, with the defenses and punters as the stars of the show? Or will Sexy Rexy's defense dare Tebow to air it out and find a willing adversary? Some are suggesting that Rexy's D won't allow the Broncos to run the ball with any sort of success, while the extra-short week (the Jets played Sunday night) and travel across two time zones and up to altitude could help to level any talent deficit Denver may be facing. Let's see if the Stats That Don't Lie will offer any hints:
