Well, Jaylen had a very good half - some inefficiency aside - but he's the only guy who looks remotely comfortable in the role he's been asked to fill tonight, with the exception of Hauser. A lot of these other guys are having to play beyond their capabilities.
One note on Jaylen: I'd like to see him move more off-ball. I feel like this is one thing Tatum has greatly improved at this season, and it's important because lesser guys are able to contribute beyond simple catch-and-shoot opportunities if the whole defense is preoccupied watching Tatum. Smart can't break down a set defense very well, but he absolutely can break down a defense that just s*** themselves because Tatum flashed across the lane. Brown doesn't have the same gravity that Tatum does, but he still has enough to bend the defense with off-ball activity and I want him to learn that. Making teammates better is about more than just being a better passer (though that's certainly a part of it).
