To some extent that is true (he's a pocket passer and I can count on one hand the number of times he had an actual pocket to pass from last night), but the nature of the CFL allows for a QB to create something out of nothing. It even allows for the spectacular to be created out of disaster. Willy isn't doing that. Reilly did it about 4 times last night. Those plays are the daggers Bomber fans are so used to feeling.
I don't think Willy could ever be that kind of QB - that usually goes hand in hand with enhanced mobility powers - but he is expected to compensate by being absolutely clinical in his execution. Last night was very rookie-like for long stretches, and he's not a rookie.
As for how long his leash is, that's an awfully personal question.
