Richard Jefferson doesn't hold back. In talking to beat reporters, RJ admitted that if the Nets had kept him and Nenad Krstic, they might have won a few more games, but "I probably would have killed somebody by now." So the Nets had chemistry issues, you say? He didn't identify who he might have offed, but his relations with Lawrence Frank had soured. Krstic's knee injury? It was as much mental as physical, he says.
