We are probably his best option left at this point if he wants to up his value for next FA. We are a playoff team that he could realistically start for and we can offer more than the minimum.
I would have preferred going after Oladipo (who just signed for the minimum with MIA), but Schroder is a decent option. And if he balls out and becomes an All-Star, well, we can actually re-sign him in the offseason with our cap space.
