agree on this.
most assume that Bonner will be resigned, but forget that Spurs for sure won't want to pay much more than they already do. if another team offers him 3.5-4 million, I can't see the Spurs match.
Bonner is a great guy, but his role will never be bigger than 15-20 minutes IMO.
Bonner is already 27, so this will be his chance to get a longer term contract. if another team offers him like 3years/10+million, he will likely bite.(and Spurs likely not match)
he never made the big bucks and even if he is a very low key guy, he won't leave 5 or more millions on the table, just to be a no.8 or no.9 player with the Spurs.
