when the cavs are at full strength, their bench is not sad. we'll just say that their starting guards are Pavlovic and Hughes. Leaving Gibson on the bench to provide a little scoring spark. The other backup guards are Devin Brown, Eric Snow, Damon Jones, and Shannon Brown. Devin Brown is good ballplayer who doesnt really excel at one aspect but is good at all, and versitile. For what Snow lacks in the offensive game, he is a top notch defender and almost a coach on the floor/bench. I can't really stand Jones being on the team, but he still can shoot the 3. The backup big men would be Varejao (when signed), Dwayne Jones, Cedric Simmons, Donny Marshall, Ira Newble, and Demetrious Nichols(will be in NBDL when Varejao signs). Newble is a pretty bad player, but is adequate on the defensive end and as LBJ's backup he doesnt see many minutes. Varejao could start for many teams and his energy is unmatched coming off the bench. Jones and Simmons are young and talented bigs that can provide some athletic ability off of the bench. Marshall is getting old but can still hit the occasional 3.
The Cavs are built on defense and rebounding, and that is what the bench consists of.
