Ekhm, assist/turnover ratio:
Raymond Felton: 2.39
Jeremy Lin: 2.10
IMO a very comparable score, but in the playoffs:
Raymond Felton: 2.76
Jeremy Lin: 1,00
Moreover, also in the playoffs:
Raymond Felton: 14.1 ppg, .444 FG%, 3.4 trb, 4.7 ast
Jeremy Lin: 6.9 ppg, .250 FG%, 3.4 rpg, 3.4 ast
Felton is a way better PG, especially playing under pressure, Lin lost his starting spot during the playoffs for a reason. And to make it even more complete:
Ramond Felton: $8.54M remaining on his contract through 2014/15
Jeremy Lin: $20.12M remaining on his contract through 2014/15
You do the math. Felton may not be an all-star caliber point guard, but he simply outplays Lin... and all that for much much less $$$.
