No offense, but the thread le is somewhat misleading. Stein stated that he has sources that say that the Spurs "have not yet ruled out" pursuing Fisher - not that they are after him. The Spurs front office would not be doing their due diligence if they were to come out and say "No, we will not look at Fisher as depth at PG considering that Portland is holding up things with Mills".
It appears now though that OKC has entered the fray and are considering pursuing him as well. I wonder if they have good hospitals in OKC.
