Don't exaggerate who McConnell is. There's a reason he's a backup. He's a role player who had one of the games of his career last night. Hats off to him.
So is Rozier... and Smart... and Morris... and everyone else not named Horford, Tatum or Brown. It doesn't mean that he can't do it again.
He presents a problem because he's an actual basketball player unlike Ben Simmons (who I still don't understand what his function is on an NBA team). I have been one of the people on this board that has been very confident in a Celtics series win, but I will say this: The Celtics are going to have to figure out how to keep him out of the paint or they
will lose again. It's just as simple as that. Once he gets into the paint, it enables their entire offense (something that hasn't happened in 3 games). He can either score, alley-oop Embiid, or kick out for an open 3.
You don't gameplan for TJ McConnell.
I guarantee you that they are.
