Um...geez...do you HAVE an imagination? Let's see...without Avery...that the Spurs would not have won the first Championship (and they would probably not have won the two additional ones without that first one). That the Spurs, AS A TEAM (if you can grasp the concept) would not be where they are right now. Timmy might have/most probably would have signed with another team when he was a FA. David may have (probably would have) retired earlier than he did, especially if Tim Duncan wasn't a Spur. Manu would probably be playing somewhere else, and so would Tony (more likely, no one would have heard of either of them, still); Oberto would still be in Europe. For sure Michael Finley and Nick Van Exel would not be here; the only reason they are here now is because they want a ring/the opportunity to play with Tim Duncan (even if they do not show that on their list of reasons for signing with the Spurs). , we may not even still have Pop as a coach if they had not won that first Championship.
Generally speaking...I hate people who make being an asshole into a vocation.
