Chart below is from PFF for 2010\2011 1st round picks by selection order. Note that RBs have double the average failure rate, making Ivory a smart move. And why I didn't like the Revis trade with only 50-50 odds of success on a draft pick at corner.
Last, note 0 of 3 drafted TEs have made it, so good job avoiding TEs in round 1. Smart moves Mr. Idzik!
I'm guessing Idzik isn't making personnel decision based on unbelievably small/useless sample sizes.
