No one knows. If the Bills had taken Smith then this forum would be filled with apologists saying how he is a disappointed kid and this has no bearing on how he will perform on the field.
But the Bills took Manuel, so some feel the need to piss on the pick that most of the talking heads (and hair) would have preferred.
If, God forbid, in 3 years Geno is kicking ass and taking names while Manuel looks like Losman no one will remember threads like this and will demand he be cut and whoever the GM is be fired.
It's just the post draft kool-aid talking, no harm done
