You're right...it was better.
Consider: the flow of the game (which is immediately one of the NFL's greatest ever), the fact that we've been arguably the worst team in the NFL the past decade, that Alex Smith and to some extent VD have taken endless s**t, and that those two players combined on the play that delivered the team (and themselves) from purgatory. Remember, when TO caught the pass we expected Young to somehow get it done, because that is what we 49er fans grew accustomed to over the previous 20 years. This, on the other hand, was Alex Smith. ALEX SMITH!? QBing a team that did nothing but break our hearts (or some times not even compete) for most of the past decade. This was Vernon Davis, the guy who loves to jump catch and can have inconsistent hands. Everyone in America was still thinking, up until that throw, there is no way he's getting this done--including me. It's not that I wanted him to fail, but rather, the ineptitude of the last decade made it very hard for me to really, truly believe.
Plus, the resemblance is uncanny. I immediately thought of TO...it was almost the same route, just about 8 yards closer. But same spot going in to the same end zone absorbing a huge hit and somehow holding on to the ball....and then the crying. C'mon Man.
