just for entertainment, here are the stats of davis and powe versus cleveland this year.
davis
16 min, 8.8 pts, 3.5 rb, 81.3% fg.
powe
9.3 min, 5.8 pts, 1.8 rb, 58.3% fg.
perhaps it is simply an issue of matchups. maybe various combos of smith, varajao, and Z maybe too much for powe under the basket?
davis has a bit more outside shooting range and speed, not to mention stength to hold his ground. powe is pretty much restricted to scoring directly under the basket, which plays into the blocking abilites of cleveland's front line.
but i am still glad the celtics have BOTH powe and davis. each has different talents and limits. having both on the bench may allow the celtics to play matchups better.
