In response to Eldunker's comment:
Monroe isn't perfect, but he is far from the bum as being described here.
Monroe is one of the better big men in the NBA. Every single big man has serious flaws. But he is young (24), big (6'11"/250 lbs); healthy (hasn't been seriously injured in 4 years and plays 30 min/game) and still has upside.
Like PER or not, it is the only statistical measurement of a players overall value. Monroe's PER is 20.34 which is quite good. (Rondo's is 15.34 which is quite average).
Monroe averages about 16 PPG, 10 RPG and 3.5 APG. He see the court well, has decent hands, passes well, is unselfish and athletic enough to spin, drive, post up, and run in transition very well.
Yes his D stinks, especially trying to cover 4s because of slower lateral movement. Can this improve with specific training and development? Maybe. He doesn't have a very good outside shot either. But his natural position is Center not PF.
At center, he is not a rim protector and can't defend Bigs very well. THAT IS HIS FUNDAMENTAL PROBLEM.
But Is that much different than acknowledging that Rondo can't shoot or defend other PGs very well?
All things considered, a Big with flaws is more valuable than a Guard with comparable flaws.
Sweeten the pot with a future 1st round pick or another player on a rookie contract and I'm in.
