I didn't think they were going to tank, i never understood that idea given the talent they have. But I also didn't think they'd be THIS good. Maybe 42-44 wins, right now they look like they might challenge for 50.
The emergence of Walsh, Queta, Minott and to lesser degrees the solid contributions of Scheierman/Hugo are a complete game changer. This team NEEDS cheap contributors to be able to keep together the Tatum/Brown/White core, and they've found some this year. Walsh especially looks like he may be the glue-guy 5th starter 3+D wing they desperately need.
Add one more rotation center, not even a starter just another roughly Queta level guy to split the minutes at center with him. Get JT back. Do those two things and I think they could make real noise this year. The east is so bad they may challenge for it even if those two things don't happen.
