In the article about us not getting Kyrie, the author stated that Cleveland would only make trades that allow them to still make the NBA Finals.
I think this trade still gets Cleveland to the Finals. Hell, I think whatever team LeBron is on, as long as he is in the East, he is getting to the Finals. Tobias and LeBron could be a fun combo playing together, as both as long and athletic with decent 3 point shots. Both can switch easily on defense with the 3/4 and sometimes 5 position.
I don't think Cleveland would care much for losing Channing Frye. And they would get a PG who is good.
I don't see Cleveland getting passed GSW without acquiring anyone short of DMC/Anthony Davis/KAT/Kawhi. None of that is happening.
EDIT: Link not working. It is a Reggie Jackson/Tobias Harris trade for Kyrie Irving/Frye. We'd have to throw in some draft picks, of course.
