Let this be a reminder that we can't assume a W just based on talent level. Fringe NBA players are out to prove that they belong and will close the talent gap with effort if we mail in a game like this one.
The Grizzlies have three decent players on their active roster, and that's only if you're giving Aldama more credit than he probably deserves. But they left everything they had out there and it was very nearly enough to beat a Celtics team that played unfocused and disinterested for much of the game.
