--Ability to extend plays
Except one does it in a controlled manner and with a purpose and plan....and generally gets really good results. The other "runs around" and "hopes" for SOMETHING to happen SOMEWHERE...SOMEHOW....SOME TIME. It's all "magic" ya know.
--Arm strength is similar
Which matters little without accuracy (which comes from form/technique -- which one has and one doesn't) but I'll concede the point on the grounds that one will be able to maintain their arm strength throughout their career (again due to form and repeatability) and one won't (already has elbow issues).
--Quick feet that allows them to change directions on a dime
I already stated how much more lateral quickness and balance Wilson has compared to Manziel, so we'll have to disagree here. Manziel had escapability in college....not so much at the NFL speed level.
--Ability to make throws from many different arm angles
True. Except one is happening only when forced to by the play or position he's in from time to time and the other is because his throwing motion is garbage and very inconsistent from throw to throw.
--Make plays when nothing is there
Wilson might be the best I've EVER seen at this. Trying to put Manziel in that category.....man I dunno. Talk about a reach. I haven't seen much of this from Manziel in the pros other than the random chicken scramble.
Ah the ol "clutch" argument. Anybody with a knowledge of analytics knows there is no such thing as the clutch. Players play at their talent level. The idea of the "clutch" is nothing more than fans projections of players performance during important situations, where their performance follows the normal randomness based on their talent that any other game situation would.
Michael Jordan was not "clutch". He was good. Just because he was good at important times didn't make him clutch...it made him...good, just like at any other time of the game.
--Keep eyes downfield while scrambling
I'll give you this one. It's one of the very few things Manziel actually does well. At least when he doesn't have his back turned to the play and is running for his life like a chinese fire drill.
