At this stage in the draft, you're looking to find depth anywhere you can get it.
The Broncos' selelction of Matt Paradis isn't going to blow you away. He wasn't even the best center in a below average conference (Mountain West).
His size is suspect to be on the interior of the line; he's not particularly quick or fast; his reach is also not great.
What he lacks in size, though, he makes up for with his technical abilities. He's rarely out of position or caught leaning.
Here's some tape of Paradis. You won't see a lot of bad plays here because it's a highlight reel, but you will get a sense of how much of a grinder Paradis is:
Add Paradis to the list of guys who can also play a little guard when needed.
Will he stick around past camp? Your guess is as good as mine.
