regardless of whether or not Wallace handle this correctly, who is he referring to as being selfish and focused on padding their stats? Green agreed with him so I'm assuming Green is not one of those players. Bradley took 14 shots, and Lee and Bass each took 11 shots, so I would guess those three may be the guys he referred to. Crawford only took 1 shot, so it can't be him, and Faverani and Sullinger each took 6 shots, so it's unlikely to be them.
IMO, Bradley as our starting PG taking more shots than anyone on the team and shooting 4-14 with just 2 assists is the primary culprit, and he is playing for his next contract this year.
