I think the quarterback concern stems from the fact we are strong in all facets of the game except quarterback play (OK, maybe kicking is mediocre also). If we were an Albany-level team at this point one would not really notice our QB as a major weakness...but our D, our receivers, our two running backs, our O line, etc. are all top-flight FCS. Just like last year.
A top flight FCS team wanting to make headway in the playoffs has to have a QB with either a rocket arm or a decent arm with real wheels (plus the physical toughness that our QB does have). In all honesty, I am not sure our QB starter or our QB backups fit either of those two models of very successful FCS quarterbacks.
