The Celtics defense was a focal point of discussion for the Sports Tonight crew on Friday night.
Tim Welsh joined Gary Tanguay and Greg Dickerson to discuss the Celtics' defensive woes against the Rockets.
"It's the guards fault. The guards have not played consistent defense all season long." said Tim Welsh, "I think the defensive character of the guards has not been good all season long. It starts with Rondo and also Jason Terry as well."
Is this something Doc Rivers can fix?
"He's proven he can change it in the past, but with a little different cast of characters." continued Welsh, "It's a team thing. It's a team mindset. If you have one weak link, or two weak links it's a problem."
