Yeah. There are also different ways to grip the knuckleball in order to change the way it dips and breaks. Different grips change the motion of the pitch, although the idea of "no spin" stays the same. I've always that that a knuckleball/fastball pitcher would be absolutely lethal in the league. If he could completely mix the two pitches up, especially given the tremendous velocity gap between the two pitches, hitters would be completely off.
Yoda is correct. Mo doesn't have the arsenal of pitches to be a starter. Starters should have at least a fastball, breaking pitch (curve/slider), and a change.
