Why is the consensus that Leon has reached his peak already and Glen still has room to grow?
Baby has a wider range of skills: at varying points, he's shown the ability to shoot, drive, post-up, draw fouls, defend both frontcourt positions, show on pick and rolls, rebound (occasionally), pass the ball nicely and even grab some steals. Powe has demonstrated more consistency in a much smaller range: rebounding, defending 4s and pick and rolls, blocking shots from the weakside, finishing strong, drawing fouls and posting up. He hasn't shown any passing ability, ballhandling or jump shot. He's also older and he can't promise any productivity increase based on weight loss.
