Only because the last few seasons have been so disappointing in terms of having our hopes dashed over and over in terms of individual perfomances and chemistry problems... compounded by injuries, sure, but we've really had a massively high player turnover the past few years, and no-one's really shone when they came to Houston, even a few downright failures. This season we can be anywhere between 40-60+ wins, first round playoff exit to nba finals...
I think the only reason people picked Snyder is that they haven't seen him play much. If they had, they would know that he's a reliable option at SG who could be a starter on a weaker NBA team. He's proven himself to be an above-average NBA guard, there's little chance of an absolute bust.
