The problem as I see if (from the Cavs pov) The Warriors are a "team" while the Cavs are a potpourri of players that can look good when all is going well, but when the pressure is on revert back to their tendencies.
Lebron....doing all he can but one dude is not going to get it done alone.
Irving....too much iso ball weak on D he really isn't a point guard sure he can score like crazy, but while he is doing that his teammates are standing around and getting uninterested
Love...listen to the commentators if he hits his first shot he (historically) has a good shooting night. How wack is that this dude has no heart IMHO he should be way better. But if your confidence is so shaky that your first shot of the night dictates your overall performance, that's not good for postseason play and the level of competition.
Smith...this guy could really help, but again he is a mental midget he can make crazy shots, and then follows it up by a totally bone head play. sorry but you cant count on someone like this in the heat of battle at the highest level of competition
Their bench has some nice pieces (deli, scumpert, frye) but either the starters or the game flow limit their effectiveness.
the cavs went 3 crazy down the stretch of the regular season and that worked great in one game series or in the Eastern side of the playoff bracket, but when a team defends the 3 and doesn't just give you wide open looks those shots just don't fall like they did.
Bottom line I just think the Cavs are flawed as a "team" when compared to GS.
just my .02 and yes I am totally bias :)
