Last season, Mack took 95 field goal attempts, Chris Johnson 194, Trey Burke 634, Raul Neto 418, and Trevor Booker 388 for the Jazz. They were five of our worst seven players as far as TS% is concerned, having ranked 373rd, 340th, 291st, 222nd, and 211th respectively in the league. Two of these guys are gone in Burke and Booker, Johnson should be gone, and Mack and Neto really shouldn't play unless Exum or Hill get hurt imo.
Add Johnson and Hill, assume a tiny bit of overall shooting growth since our guys are so young, and add in infinitely better point guard play this season which should help with spacing and therefore shot selection and efficiency, and our offensive numbers could be significantly better this season. Now consider how much better we could be on defense with a healthier frontline and the additions of Exum and Hill. Pretty scary, right? Then, factor in just how bad we were in tight games last season and this team could make a monster leap. I'm predicting we go 51-31.
