Buck3ye5 is the reason a lot of Ohio State/Cleveland fans get a bad rap. Complete homerism like this doesn't bode well for people who already have to defend their stance on their favorite team. That being said, onto the trade.
Shaq has been getting better and playing better as the season has progressed, is it him fitting into a role, getting into better shape, just needed the first half to get going? That remains to be seen as the second half has yet to be played. The issue is just how durable is Shaq. You guys are mentioning all these other centers who are outplaying him, and yet he's twice their age. Of course the big man is going to have trouble keeping up.
I'm not defending Shaq's play because it has been atrocious through most of this season, but he is there for one reason and that's to occupy bigs so Z/Andy/J.J. are not getting out muscled and burnt. To think that Dwight Howard didn't have an effect during the Orlando series is asinine. All of what Orlando did centered around Dwights will to impose himself anyway he wanted down low. Cleveland failed to defend the perimeter, and failed to defend the pick and roll being preoccupied with Dwight. So they went out there and got the "plug" to their "leak" on defense.
As it stands now, I like where Cleveland is at with their roster and it'd be a shame to sacrifice this chemistry for anything less then Amare. Personally when I look at the pieces involved (Amare, Jamison, Murphy, Maggette) the only one I like is Amare followed closely by Murphy. Cleveland doesn't have to make a move now to be effective but as others have said, if you can get something big for cheap, you take the deal.
