Right now, from the looks of it you are considering the trade solely on Kobe because Deron is way better than TJ IMO. What you can do is try to get someone from the FA list. I just picked up Eric Gordon and he has been playing beautifully for me points wise, even before Baron got injured. You would probably get a slight increase in points, but that is about it. In the last 15 games:
TJ
.346 fg .714 ft 0.0 3pt 1.7 reb 4.0 assists 0.7 stl 0.7 blk 7.7 pts
Kobe
.566 fg .889 ft 2.3 3pt 5.0 reb 4.7 assists 1.7 stl 0.3 blk 30.7 pts
what you have
Deron
.435 fg .833 ft 1.0 3pt 3.0 reb 10.8 assists 1.5 stl 0.3 blk 16.8 pts
Durant
.468 fg .886 ft 1.1 3pt 8.6 reb 3.7 assists 0.7 stl 1.0 blk 23.3 pts
total of main categories
What you get
6.7 rebounds, 8.7 assists, 2.7 steals, 1 block and 38.4 pts with a so/so fg and .80 ft%
What you have
11.6 rebounds, 14.5 assists, 2.2 steals, 1.3 blocks and 40.1 points with a higher ft%.
now make a decision.
