Save the TPE for a potential Gobert sign-and-trade plus picks during the offseason.
The other, more remote possibility is the Clippers collapse and Kawhi wants out and wants to take out LeBron/Lakers in the green, in which case we use the TPE and picks to make a sign-and-trade happen after Kawhi declines his player option (maybe negotiate a gentleman’s agreement where we subsequently send Kemba to the Clippers for a heavily protected second if that’s what it takes to get them to deal with us instead of the Heat/Bucks/76ers/Raptors). Kawhi clearly has contingency plans considering he signed just three years with a player option on the third year. If they do not win it all, and certainly if this season is a repeat of last, I bet he’s available.
Waiting for a potential superstar in the offseason, rather than blowing it on second-tier talent right now, is by far the best option here. The second-tier talent will still be available come the offseason...
