What will it take for Spurs to he "serious" players in the LMA sweepstakes?

Kawhi gets his $

Manu and Tim both come back but at what price?

Danny Green comes back? At what price?

Would it help if we did a sign and trade with Tiago?

I want realistic answers from somebody that understands the cap. I've heard LMA talk but that's mainly with the retiring of Tim. I just want to know what it'll take for us to be in the mix
