so basically now that baby's back, it would be fair to say that the choice would have been between bringing leon back or signing shelden williams. leon has somewhat proven himself as a reliable rotation player. williams has so far been a flop, being the #5 pick that he was. but leon is coming off another major surgery and it's uncertain if he could regain his old form, while williams is available right away and is healthy. williams was expected to do well in the nba, coming from a high profile college, and having been named defensive player of the year in college for two consecutive seasons. leon on the other hand dropped into the 2nd round because of uncertainties in his health (yet again).
three years ago, powe was the "underdog" who got a chance to play for boston and did well. now, williams is being brought into that exact situation. he is the "flop", the failed lottery pick who couldn't do well in mediocre teams. given the chance to play with the big three and sheed, will he finally evolve into the player that he was touted to be? no one knows for sure.
in a way, both powe and williams would be "projects" for their new teams. will powe overcome his injuries? will williams benefit from a change of scenery? boston chose to go with williams because he is ready to play now. he certainly has the pedigree to make it as a legit nba player. the question now is if he would bloom in the celtics' system.
having said that, for NOW, i guess you can say that powe vs williams is basically a wash. if williams becomes a solid rotation player, then we did the right decision. if powe comes back to be the player that he was before getting injured, then we screwed up. we love leon because he was a celtic. he bled green. he walloped the lakers during the finals. i'm sure we will feel the same for williams once he proves himself. with the injuries to kg ang scal last year, we needed to bring in a healthy body who could step in right away. that is the main advantage that shelden williams has over powe right now. and i think that is one of the major reasons why shelden is a celtic right now, and leon is not.
