Reggie was NOT fast and certainly not faster than Josh. RB ran a friggin 4.EIGHT in the NFL combines, ok? So drop this one.
He wasn't very elusive either. Think so? Show us more than a very small handful of effective jukes on film. A lot of us in the UE used to joke about how white Reggie seemed to get when he broke free.
Arm strength may have been close but not quite as strong as Josh's. Overall strength isn't even close. Josh is a much stronger man than Reggie.
The thug factor was already showing itself by the middle of Reggie's soph year. So far, no hint of it with Josh.
Unfortunately the biggest common trait they have is fumbling. Josh will either get it corrected between now and the end of Spring or CPJ WILL replace him.
And finally, there's a reason why no other D-1 program offered Reggie as a QB.
