I agree 100% with you my friend, but to be honest I think he would be a nice back PG for our team. I am Greek, and I have followed Spanoulis's career since he was in Marousi, the first small market team to make it to the Greek league finals. That's pretty big, the only other team that has done that (at the time other the big3), and its not exactly a small marker team, was PAOK under the leadership of Peja.
Even though Spanoulis is not Peja, he could be an impact player off the bench for us. And to be honest, spurs are maybe the only NBA team, that Spanoulis can some success with.
