The production similarity is damning because it was supposed to be better. They didn't risk chemistry and fanbase issues for "exactly the same". If the production is a matter of the situation then you just keep Granger because he can defend the post better than Paul and is twice the defender ET is, and you live with the offensive numbers.
For the ET deal to be a success his production, especially scoring, must be a substantial improvement. So far the 2 "swing for the fence" deals have gone tilt.
I do like that ET has had the better FG% but it really sucks not having the 3pt threat. The issue was that DG hadn't gotten dialed in from 3 either.
