I should probably just be open-minded, patient and wait, but, you know, "To thine own self be true, and it must follow, as the night the day, thou canst not then be false to any man," ... and all that.
As you're aware, the Spurs have recently made a couple of tweaks on the margins of their roster, adding a pair of former Timberwolves first in Andre Miller and more recently Kevin Martin, at the expense of Ray McCallum and Rasual Butler.
To put it simply, I am not a fan of the signing.
