If the Knicks ever had a PG, Allan Houston would have shot 45% and broken the record for 3's every other year. If you have to make a list of the best pure shooters ever, Allan Houston is on it.
He literally hasn't aged and is in as good a shape as you can be...seriously. If he needed 3 weeks to get in shape, he could and he could actually be an asset. He didn't play his last few seasons on the roster...and it's not like he ever bothered playing any defense, so he'd be fresh. Off the bench, how much more a defensive liability could he be?
He's as smooth as you're gonna be for a volume shooter. I don't even remember him bothering to come off a screen lol.
