I've watched Leach for a long time. Graham Harrell had one of the weakest arms ever in college football and put up huge numbers, Kingsbury's arm was average at best and he's had several others very similar. Will's arm is better than Harrells and at least as good as Kingsbury's. The major difference between Will and those qbs is decisiveness. Those qbs knew almost immediately where they were going with the ball. Will is still not as decisive as he needs to be and that may just be a matter of experience(hopefully). He has enough arm to run this offense but can he learn to be more decisive and take the shots down the field instead of checking down so much. Time will tell.
