We need another undersized power forward like PDA needs hair dye.
I don't want to have to dig up the numbers again, but if Thomas Robinson is an under-sized PF so are Kevin Love, Blake Griffin, Zach Randolph, Serge Ibaka, Carlos Boozer, David Lee, Jared Sullinger, The Morris Twins, Amare Stoudamire, Tristan Thompson, David West, and Carl Landry.
The only guy on our bench who's even in the same league as Thomas Robinson as a physical presence would be Eric Moreland if he can put on another 20 pounds of muscle. Among players who've been on the court for at least 200 minutes this season, Whiteside ranks first in defensive rebound % and Robinson ranks eigth. There are always going to be nights where a pogo-stick wrecking ball of an athlete will be of use down low for 15 or 20 minutes.
We should have both of these guys coming off the bench on team friendly deals right now. Along with Cousins and Thompson, that's got to be one of the best front-court rotations in the league.
