Beno is cheaper, and yes, slower. He doesn't create off the dribble to make space for his own shot as well as Mo. But he passes the ball well, will hit the open three, and has the ability to create for himself and teammates. You could claim Udrih is a worse defender, but let's face it, defense isn't exactly Mo's forte either.
And Beno isn't a turnover machine. Against Minnesota, Mo earned every point of his -22 +/-. In some ways it reminded me of the dreaded 30 seconds of Nolan Smith last year, only it lasted longer and did more damage over the course of the second quarter. At least one of the turnovers charged to Joel was Mo's fault, he was running away from the ball with "all I care about is steals" Rubio defending him. Terrible. This is not a one game thing, either. It appears we've won a couple games in part due to shots Mo has taken and hit, but on balance, he will prove a liability over an 82 game season plus playoffs.
Mo: 24.4 MPG for 41.4% FG% 37.0% 3P% 2.0 RPG 4.5 AST 2.2 TO and 9.2 PPG
Beno: 16.6 MPG for 45.6% FG% 52.3% 3P% 1.8 RPG 2.4 AST 1.3 TO and 5.8 PPG
Penciling out Beno's stats with Mo's minutes gets you: 2.65 RPG 3.53 AST 1.9 TO and 8.53 PPG and that's on the Knicks, who don't pass and don't create open shots for teammates. Beno would excel in Stott's system, as he has been money hitting opens shots against the Blazers when playing for the Kings for years and is again shooting over 50% from beyond the arc this season.
Mo for Beno. Admit Williams is a bad fit and make it happen Neil.
