Richardson gutted through 34-plus minutes, scoring eight points, none bigger than a 16-footer with 47 seconds remaining that gave the Sixers a three-point lead en route to 104-101 win.
Also, Spencer Hawes tweaked his left knee on Saturday when he went to set a pick on Russell Westbrook and his foot stayed planted while his knee moved inward. While Hawes was a little tender Sunday, he played just under 21 minutes.
"The knee just kind of twisted a little bit," said Hawes, who scored six points. "It was cool while I was playing, I could feel it a little bit. It was a little stiff [Sunday pregame] but I came in and got the treatment and got it moving, so it's not a big thing. It's not weak, just a little bit sore. The big thing is I just have to keep it warm. I don't think it's a big deal."
Calling all bigs
Before Saturday's game, general manager Tony DiLeo addressed the media and said, in a nutshell, that Sixers don't know when Andrew Bynum might come back and they would have to move on without him. Sunday, coach Doug Collins said that rookie big man Arnett Moultrie would be getting thrown into the mix more.
"Arnett's got to get out there and play," Collins said. "We've got to get a little bit lively out on that front line and bounce around a little bit and rebound. I'm sure he's going to get tired and a little nervous and angst. But we've got to see what he can do."
On Sunday, Phoenix threw out a starting lineup that included three players 6-10 or taller in Michael Beasley (6-10), Markieff Morris (6-10) and Marcin Gortat (6-11). The tallest Sixer in the starting lineup was 6-9 center Lavoy Allen. Adding to the Sixers' vertical challenges was the fact that the Suns also brought 6-9 Luis Scola and 6-11 Jermaine O'Neal off the bench.
Moultrie made his first appearance Sunday with 2 minutes and 4 seconds left in the first quarter and played a total of just over 7 minutes, but failed to grab a rebound, something Collins noted after the game.
Markieff back home
Prep Charter product Markieff Morris made his third consecutive start for Phoenix and grabbed 10 rebounds to go with eight points. There appeared to be quite a few members of Morris' fan club among the 14,518 fans at the Wells Fargo Center.
