MOBILE, Ala. -- The first day of practices for both the North and South teams at the Senior Bowl kicked off on Monday, following the height and weight measurements for every player in attendance. Let's take a look at some of the prospects who stood out, and how the rise and fall of certain players and position groups could help shape the 2014 draft.

1.The 2014 QB draft class isn’t as deep as we thought it would be

We’ll preface this section by saying that it isn’t intended to be a slam against the QB class as a whole or the six quarterbacks in attendance this week in Mobile. In fact, we are very interested in seeing more of what Eastern Illinois’ Jimmy Garoppolo brings to the table following his strong start to the week. We’re intrigued by the potential of Virginia Tech’s Logan Thomas and Fresno State’s Derek Carr, who had a very good day of practice (even though we’ve been concerned with some of what we’ve seen of him on tape – more on that in a bit).

But what at times during the 2013 college football season appeared to be a very deep crop of quarterbacks has begun to thin out considerably, which could present problems for NFL teams looking to draft a QB.
