Exactly! It's what the QB does when under pressure. Some simply melt(Boller) while others move around and make something happen. One thing that I noticed tonight was the way that Smith was looking down the field when he was scrambling. I can count the number of times I have seen Boller do that on one hand. It's pretty sad when a rookie can handle that type of stuff but your 5th year QB can't.
Yes it looks bad when your qb has to worry about the pressure of third stringers; but the real point is that Smith handled the pressure pretty well and manufactured plays behind the same atrocious line play that Boller couldn't muster anything out of.
Smith seems like a player, Boller is more of a robot.
