SEC defenses how well will the spread work at a small school?

as many of you know Arkansas has new coach Bobby Petrino. He uses a balanced offense but wants to throw it appears at least 50% of the time. Exactly how well does that work at a school that does not produce much instate speed such as Lsu or Florida does? if Lsu , FL, Bama, Georgia, some of them have 40 players each year *on average* that run 4.5 or under, and ark can only average 15, don't they have to use most of that speed on defense and figure their receivers won't get enough space to consistantly pass with success in this league? Do the numbers suggest that even if you find a great qb and develop him well that even he will throw enough interceptions that you probably won't win much against that conference?

is our only hope that Petrino can recruit almost equal speed with skill out of state which has not been done recently if we want to win the SEC?

lastly, does anyone know if Petrino has the genuis that he can over the course of a few months develop a running game with this 8 guys he has catching passes each game to adjust his offense to an upcoming defense that he thinks can stop most of his passing if one of our QB's goes into a playing slump
