Funny enough I don't think you improved the team but I also do think you made them any worse.
Yeah, I have a hard time answering whether the Fake Celtics are better than the Real Celtics.
I guess ultimately, I go Fake. Our current offense is broke, so it's hard to imagine it getting too much worse in Edgar's universe. Meanwhile, I think the defense and rebounding would be improved, especially when Felton is in instead of Jameer (although Jameer is rating out pretty well defensively this year).
So, the team might continue to have a stagnant offense, but with improved rebounding and arguably an even better defense, this team could get back to elite status if it enters the playoffs rested and healthy.
