Tatum really hasn't. His usage is up. For young players, normally that drops their efficiency a bit as they expand their game. He's becoming a creator. Growing pains. He is a big time scorer on the wing though. It's easy to see how he will be a 25 point per game guy in a few years.
Brown suffered the most from the lack of rhythm in Cs offense in the early season. Although physically gifted, he still doesn't have a great feel for the game. CBS rhythm offense helps with his feel, but when their offense was a mess, he struggled to get good shots.
Still, he's one of the best on our team at getting easy buckets in transition and defending the perimeter. He's still the first line of defense against the elite swing scorers like Durant, Leonard, and James. Morris is good and Smart can be used in key moments, but for the doldrums of the game, we need Brown's strength and athleticism to make life difficult for those scorers. His defense against those scorers are the body blows and Smart's defense is knockout blow. His defense is the 230 pound rb that hits the line for 3 yards a carry and Smart's defense is the 4.3 40 back who takes it 60 yards for a touchdown.
