Yes, absolutely. Which is why the Bills offseason plan to get Josh some competent players around him was so important.
But the risk of a bust with a guy like Haskins is so high because you've seen him play what, 3 real games of football in his whole college career? People get blinded by six TD games against Indiana or whoever, but those are the games that should be thrown out the window entirely. See also: Cardale Jones, Aaron Maybin and Da'Rick Rogers; other one year wonders who had most of their stats against vastly overmatched opponents.
And he's really fun to watch. Wilson is absolutely one of the best players in football.
