I ultimately think no. Not to be a negative nancy but Cassels inability to cycle his progressions is unbelievably bad. With the addition of Hillis, boss, and mostly Daboll I think we will be a run first short yardage offense.
I hope I am wrong and definitely think our O can be great this season. But right now and with Cassels roller coaster time in KC, for me it is wait and see. (and I didn't mean for that to rhyme, But it worked out.)
