Basically tonight is a bona fide Cavs win in the 06/07 season.
Had a lead, lost their concentration, and pulled it out after making it much harder than they had to. Think back on this season, how many teams did we blow out that allowed us to rest our starters for an entire quarter? Maybe 2. This is a team that classically plays down to their competition and easily forgets what gets them leads.
It's not a good recipe and I think this team has passing interest in this series right now and just wants to get onto round 2. This team thinks it's like the Lakers teams of Shaq/Kobe that just turned it on when they had. Whether or not the Cavs can remains to be seen.
When they are on, the Cavs can play and beat anybody. However, about 60% of the time they do just enough to win and that's not good in the playoffs.
