I am the guy that calls the Jefferson football games. I was actually in Burnsville tonight for the big Kennedy/Jefferson game that was moved to Burnsville due to poor field conditions in Bloomington. Hopefully this spurs them to finally install field turf at the stadium since about 1000 teams use that field - but I digress.
Marcus is actually right around 6' tall. He has good speed and good agility. Nothing "reggie bush" esque from him - but good ball skills. Unfortunately Jefferson is horrendous this season and he hasn't gotten to show off his skills.
The new Jaguar QB threw for more than 1000 yards and 10 TDs in basically 3 games to open the season (why wasn't this guy playing for them last year)? But he was injured in game 4 and the offense has sputtered since - including 2 home shutouts (40-0 and 34-0, and a 40-6 defecit before two meaningless TDs tonight to 2-5 Kennedy). Goes to show you how important this QB was to their team.
Moses had a subpar offensive line last year - but this year's offensive line for TJ is way worse. Moses is a great leader on any team he's been on, an outstanding student, very intelligent, and has great size and arm strength. Not to mention well-spoken in interviews. No need to worry about any off the field issues either. Too smart and too well-raised by his parents for that.
That is why he has been projected so high by the scouts. He used to be a dual threat QB but with his size at 260 lbs he can still move, but I wouldn't describe him like Gray as a dual threat.
Footwork, and more importantly, accuracy are his downfalls. Footwork can be taught, but accuracy is more difficult to teach. He missed many wide-open receivers in HS, and while some of those throws were on the run - we can all agree a college QB has to throw on the run as well. His QB to Int ratio was very poor due to the accuracy - and this was with the same receivers and better offensive line than the starting QB this year had to work with.
Moses is also not "raw." This is the biggest misconception with him. He was a starting QB for 4 years in HS - a chance so very few players get at the prep level. His dad was an NFL player - so he's had more opportunities to develop in football than 99% of the kids playing the game.
Moses did play some DE in HS - but wants to be a QB. He has all the physical tools of a pro-style QB. If his footwork and accuracy dramatically improves the sky is the limit. As many know I've been on record as saying he won't be a Gopher QB because of these deficiencies. As I will say again I sincerely hope I am wrong and he is the QB everyone wants him to be.
