Harrison Barnes on Spurs’ Stephon Castle All Star consideration

As Warriors All-Star Stephen Curry recovers from a knee injury during the NBA’s big weekend, the veteran Spurs forward Harrison Barnes says Stephon Castle deserves All-Star consideration to replace SGA. Barnes also backed the other half of the Spurs backcourt in De’Aaron Fox as a second option.

“It would be criminal if he (Castle) and Fox didn’t look. We’re No. 2 in the West,” Barnes said. “I think because of what we’ve done, for the teams below us that have had two All-Stars, I don’t know a case if we’re talking about the impact of winning and playing high-level basketball, why any of them shouldn’t be drafted and/or considered for those spots.”

Harrison Barnes argued that at least one of his two Spurs teammates should have been named an All-Star backup to Steph Curry:
