I attended the Elite 11 event in Columbus and thought I'd share some of my thoughts. Let it be known that I have no real experience beside watching football and my opinion means absolutely nothing.
I spent most of my time stalking Shane Morris. Gunner Kiel and Zeke Pike were also in his group of 20 or so QB's so I could compare the three of them somewhat. I guess I'll sort this by player.
The most impressive quarterback to me. He's a big kid, tall and has some muscle. His arm wasn't the strongest, but he was probably the most accurate. He showed good touch on the long ball and he hit his receivers very well. To me, he had the best day.
Also impressive, although less so than Gunner. He's also a big kid in terms of height, but he is pretty lanky and has some filling out to do. He has a VERY strong arm, second in his group and better than Gunner. His accuracy was a little off compared to Gunner and a few others and his balls began to wobble a little as the day wore on. I even ended up with a few of his passes in my hands as he missed on a few outroutes. He is very smooth in his throwing motion. Very good day, especially as a sophomore.
Good day, but not as good as the other two in this post. He's bigger than the other two, both taller and thicker. He has a good arm, but was the weakest among the three in terms of accuracy. I was more focussed on Gunner and Shane so my impression might be incomplete. He was one of the better ones in his group (behind Gunner and Shane) and it was kind of fun listeneing to his father yell "Zeke!" after every throw and give him little tips.
Overall, all three were impressive. Kiel looked the best among the three, but you have to take into account that he's a year older than Shane. I don't know much about footwork so I can't really judge that, but no one had any obvious issues. I liked what I saw from Shane and I think the future is bright.
Feel free to ask any questions and I'll try to answer them. I shot a little video on my phone, but it may not be of use unless you like struggling to make out players from 30 yards away.
