There are some that should have tried to go pro that did not. The TEs, Eisworth, Probably more should have went pro. I truly hope they do not get hurt and ruin their football careers.
I personally do not think that Eisworth would have gotten drafted. He was a dynamic player as a hitter in run support, but after the shoulder injury, they moved him to FS and he's not fast enough to play there in the league. Still a really good college player and a great leader, but IMO he's a UFA in the NFL. Rose and Kolar would have gotten drafted but there's a chance they can move up a round or two with another year.
Super Seniors from what I can tell are Eisworth, Assalley, Dunn, Foster. Allen and Hummel didn't redshirt initially and took the 5th year. Guys that could have declared but didn't are Purdy, Kolar, Rose, Johnson, Hutchinson.
