Frankly, we don't need JT or JB to be elite yet. We should be able to coast into the ECF without either of them dominating. One of them needs to dominate and the team needs to play well to beat NY (if we get Zinger back).
Then, to beat OKC/Min, both of them need to play well. Which they should be rested and able to do.
They completely ran out of steam against the Warriors two years ago, partially because they had such a difficult path. This year, they need to be as healthy and rested going into the finals as possible, then lay it all out.
