I went back and looked at the drafts you mentioned and it's hard to argue your point. Besides the 2014 class there are a few guys in other classes mentioned that are better than average but the bust rate was extremely high. I think a lot of teams are reaching because of needs more than anything. I follow the draft process as much as anybody and have always been dumbfounded by some of the WR selections teams have made in the 1st round.
I don’t know where you got this, but it’s 100 percent false. Not only is it not debunked, it’s more believed in by NFL front office types and analytics than ever before.
And I have Googled the issue. And my view is the overwhelming prevailing belief.
I’ll try to post some links later.
If you’d like to post some links showing otherwise, go right ahead.
The whole "offensive tackle arm length thing" has been debunked for awhile now. Just google "ideal arm length for a NFL offensive tackle" and there are many articles and studies to back it up. Scouts do prefer their linemen to have long arms but it's not the end of the world. Hell, Joe Thomas was one of the best Left Tackles in the past decade and he had 32 inch arms.
