You are all deeply underestimating this Piston team. SVG is one of the five best coaches in the league, and there's a lot of talent on that Detroit roster. The Cavs will win in five or less, but it might be a dogfight up until the end. I know the Cavs look bad compared to Golden State, who is running through Houston, but the Cavs would also decapitate Houston given the opportunity to play them in the playoffs.
I still don't think the Cavs can beat Golden State or San Antonio, but they are easily the third best team in the league. It's not as bad as it seems. I also can't see Atlanta giving Cleveland this much trouble in round 2.
