The problem is since harden left the OKC bench has been a non factor aside from occasional big games from Reggie. OKC literally has 3 options for scoring and ONE play to do so
with westbrook back.. that should help things a lot.. because that then moves reggie back to the bench, to provide that "harden" role (or at least it should)
we start out with: westbrook, lamb, KD, ibaka and adams
we sub in reggie for lamb early (say 5 min mark).. then you stagger the mins of westbrook and Durant, so they are taking rest at different periods (but you're trying keep them around 35 mins per)
with 4 guys playing 30 or more mins per (kd, westbrook, ibaka and reggie), it shouldn't be hard to work out substitution patterns were there isn't a real lull in the offense (since your integrating guys around those 4)
