What your mentioning is true to a sense, but Copeland wasnt pulled out of the game for poor defense (if so alot of our players wouldve been pulled out of the Cavs/Rockets games).
Copeland was a starter in both games, Woody was depending on his bench-players JR & Novak's minutes & scoring to makeup for a missing Melo in both games.
In the Houston game Copeland played the first 7 minutes of the 3rd quarter, because in 3rd qtr. the starting lineup had chip away at Rockets 12 point lead down to a 5 point lead with 5 min remaining in the 3rd (Tyson, Copeland, Brewer, Kidd, Felton).
Woody was not suppose to take Copeland out of the game when we were only down by 5 points with 5 minutes remaining in the 3rd.
Jason Kidd was the only player tired that needed a rest, and shouldve been replaced by Pablo (we needed a steal to bring the Rockets lead down to 3).
But Woody took Copeland out so JR could get the final 5 minutes of the 3rd quarter, then 2 minutes later Woody took Brewer out so Novak could get the final 3 minutes of the 3rd quarter. Then called time-out with 1 minute left in the 3rd with the Knicks down by 20 points.
I'm not going to go into the Cavs game we won that on another last shot.
The Knicks vs Brooklyn game with Novak out with injury ..
Copeland bigbody became a factor in the WIN by boxingout/setting screens/running back on defense .. in some games i would rather have Copeland replace Kurt or Rasheed at banging bodies in the paint on offense/defense .. in other games I would like to have a peremeter shooter Novak increase our lead.
