Most won't like this comment. It can sound like a compliment and an insult at the same time.
But I don't disagree either. This has the potential to be a Braxton Miller tOSU type situation at some point. Jalen comes across as a team first type of player. I can see him doing well as a RB/FB....not sure about WR but maybe TE?
I think the fastest he's been timed is 4.65. But he seems faster after he's had a few steps. He puzzles me about speed. Part of it is his long stride like a Vince Young, but part of it too is he's had some runs where he was flying and and has vision to follow blocks or juke a guy..... yet....he can also be ran down in the pocket a lot? Like a LB or DL will just chase him down. So it's like he has really fast speed when he can shift gears.....yet he's not twitch side to side shifty fast elusive...or fast out of the gates. But maybe that's indecision? I'm telling you Jalen stumps me all the time with his running.
Also, maybe he develops his passing ability and stays put. He DEFINITELY needs a QB Coach in this off-season however. He 'hops' in the pocket which wastes time AND makes a good bit of his throws be out of time or just plain 'off target'. His footwork/pocket technique needs refining. I also wonder why at times the ball comes out of his hand so funky. He threw some wobbly ducks last season and a couple that just went out end-over-end like a kicked ball. Those weren't tipped passes either. Are his hands too small and he can't grip the ball well? I'm not sure? Because he's also thrown some tight spiral lasers a few times too. Something with his overall release is just inconsistent.
Most of us never thought Sims would have the Senior season he had in 2014 though.....so... We will just have to wait and see how this plays out. He gets better and starts for 4 years or Tua/Mac overtake him this year or next.
I don't forsee a 'slump' but it's possible he might or already has hit a ceiling passing. I'm going to hope he hasn't. I hope he gets extra QB coaching on technique, puts in work on timing with the WR's and TE's and that CNS and Daboll trust Jalen and encourage him to be a bit more of a gunslinger. Not reckless but not tentative either....he's needs just a little of that Moxy that Gmac, AJ, Sims, and Coker all showed at times to really fire a pass in there in tight single coverage or throw a jump ball downfield and trust that your guy will make the play. Heck even just throw to the guy running wide open in the middle of the field on a crossing in-route waving his hand around. I'm rooting for him to take the next step.
Lastly I just want to say I really really LOVE Jalen. He was one of my favorite players last year. He still IS one of my favorites. His calm demeanor and leadership and ability to forget bad plays can't be taught. He has ALL the intangibles you want in a starting QB. He made a TON of clutch plays last year with his legs(including a TD run that SHOULD have won a NC and been a Daniel Moore print we salivate over for ages) but also quite a few with his arm. He does have a STRONG arm too....the passing problems are technical and mental imo.
