I found this to be interesting because it reveals how little we actually know about the NFL talent evaluation process. For example, how many of you (me too) were screaming for James Hurst in the fourth round? Fifth round? Sixth round? I was--all three rounds. I would have been happy to hear, "The Carolina Panthers select James Hurst, Tackle, North Carolina" in the third round.
Just some interesting reading. If you are a research scholar, you may find interest in this study, but if you are not a consumer of quantitative data analysis, this one might not interest you. It basically explains that there are too many variables at play for the experts to succeed in drafting WRs, but it has a few interesting points, such as which measures are the best at predicting a WRs success (college performance over combine and pro day measures).
While most draftniks expect Zack Martin to be gone by the 20th pick of the first round or so, his "tweener" status (G/T) could cause him to drop. Players that drop tend to have a characteristic or two that scares teams--Star's heart issue, for example. If Morgan Moses continues to climb boards (some were worried about him not being there at #28 and even mentioned trading up for him), it could push Martin down. Throw in the fact that he has shortish arms, and it is possible he becomes the fifth tackle taken. 5 players at any position in round 1 is a stretch, so there is a strong chance that the 5th tackle in the draft is there at #28.
This is an article from the Observer a few months ago. Take a look at the video. Stranger things have happened. This was covered to some degree in February, but perhaps it needs to be revisited in light of developments (Cyrus, Tiny, Moses, etc) at T.
