There is just so much risk to waiting.
1) You are willing to go from Kawhi to a Jimmy Butler type player just to wait?
2) Lebron is functionally on a three year deal - so he’s now got two left.
3) What if Ingram/Kuz don’t develop and look good? Their value goes down. What if one gets injured?
4) What if you alienate Kawhi by not valuing him like PG and he spurns you and that starts a trend? PG already said no. If Kawhi does too?
5) What if there is an injury to Bron? Kawhi? Now all your plans have really gone to and things look very bleak. Sure, injuries can happen anytime but you trade for guys healthy and then just deal with it. You don’t let superstars play for other teams and risk injuries on their dime when your plan is a 3-year window.
It’s just laughable to me that you have a chance at Kawhi, with no risk of him bolting and you won’t include Kuz/Ingram/Hart and late firsts??? I mean, what? Worst case, by trading those guys who aren’t even good yet, you would still have nearly 25M to replace them next year

? What do you think will be better: Kawhi + 25M or Butler+Ingram+Kuz+Hart?
It’s pretty damn simple.
