The only immediate change, to me, is that Stevens should have a heart to heart with Marcus Smart that goes something like this:
"Marcus, you know I've been your biggest supporter, and I love the way you've been playing since you've been back. In order for this team to succeed, we need a PG that will play with pace, and keep the ball hot. When you do this -- we're really tough to beat. Combine that with your amazing defense, your leadership, and your heart, and we couldn't ask for anything more in a floor general. Can you maintain this pass first mentality? It's going to limit you to about 10-12 shots a game.... shots that are either when you get into the paint -- where you're very efficient and get fouled a lot -- or late in the clock when the ball finds you open... but i guarantee you it's going to mean a lot more winning than losing, and your team, your fans, and your city are gonna love you for it.
There's a lot of interest in you around the league. We've turned away many offers over the years. But we need to know that this is how you want to play, and if you do -- you're going nowhere. And you should know we expect the same unselfishness from Jason, and Jaylen, and will ask them to commit to it, as well."
I expect Smart will react the right way to this, and if he does -- you keep him. Then it's a question of what we can get for Schroder, Horford, our picks, and the pile of garbage that is or bench (not you J Rich) at the deadline. If nothing much, you prolly wait until summer.
