Lol Melo is so overrated. All that would mean is less shots for Stoudemire and Gallinari. Your defense and your weak center/shooting guard/back up PG positions would still be a huge problem.
Ronny Turiaf is pretty solid back up center.
Felton
Melo
Amar'e
Chandler
Gallinari
Are all
very good basketball players.
Bill Walker
Ronny Turiaf
Landry Fields
Shawn Williams
Are all very good
role players
Now, if Melo were to go to Chicago, he wouldn't be the most overrated player in the NBA anymore, right? Melo is one of the top 5 players in the league, if you want to call him overrated, go right ahead because it just isn't true. Calling Melo overrated is so ignorant.
LeBron, Kobe, Wade, Durant, Melo. In no particular order, are the five best players in the league.
Also, we don't need a "true" Shooting Guard in this system. We have a ton of guys that can hit threes with consistency. Walker, Williams, Douglass, Gallinari, Chandler.
The only thing lacking on a roster with Melo added to it, would be another decent big man. If Walsh finds one, then we are a top 3 team in the East without much debate.
Our defense has been pretty solid this season. Felton is a very good defender at his position, and Fields can guard most SG/SF. Amar'e isn't bad either, and the only thing Turiaf does well is play defense and rebound. Our style of play is naturally going to give up more points per game because the opponent is going to get more possessions because of all the shots we take throughout the duration of a game. We have much better defenders than Phoenix did under D'Antoni.
