Geno Smith has adequate arm strength. To me, it is a pass/fail event. Can he put it on enough of a rope to fit it into tight windows before the defense can react on a 10-15 yard route? PASS. I have seen it several times this year.
Barkley? Not so readily. Barkley is someone who could make throwing at the combine pay dividends if he can demonstrate some tangible velocity.
Geno's accuracy and precision is deadly and to all levels of the field. That is what I want. All the big-armed guys get totally overblown, because so many of them end up being gunslingers.
