You could look at the stats, which favors leaving Sergio in, or the scoreboard, which favors leaving Sergio in.
Jerryd had a better +/- than Sergio in BOTH games without Steve Blake and YOU said that was a very important stat when judging a PG. So that means you're on the Jerryd bandwagon, yes?
BTW Greg sucks he's sam bowie 2.0, he's a waste of space, he's a bust, he's 95 years old ... did I miss anything?
Sergio is a serviceable PG on an average team. He will never get beyond his lackluster D and bad shooting though.
Sergio leading the team in minutes played! It's a career first for him. Maybe it's because we're up by 11 under his direction?
