That's pretty decent for a center.

O'neal has good hands and can score and more than adequate on D.
Upgrade over Biedrins and Ezeli on offense for sure.
You need this type of potential X-factor in playoff run. He can get hot and suddenly score 20pts in a playoff game and turn the series around.

biedrins and ezeli do not possess the ability to change a playoff game and hence the series.

Go for it!
