Heise needs to be a reliable threat to hit the 1 or 2 wide-ass open 3s he gets every game. He doesn’t have to create his own or force anything, just let it come to him. Otherwise he's not giving us anything that Watson doesn't also provide.
Not to turn it into a Watson derail, it just strikes me that they both rebound, defend, cut, and do the little things really well. To this point Nate has been getting the PT, but if he hasn't figured it out by the time Milan returns he may start losing minutes to DWat. Heise has more upside on O, but we haven't seen it much yet. If he's going to turn into a non-shooter I'd rather have Watson.
To be clear, I want both to be very successful. I would love for both of them to play to their abilities and not be offensive liabilities while continuing to do all the little things. More options are always better than fewer options.
