doubt he gambles to become RFA. one injury and his value is shot and with spurs having the ability to match offers, he could end up in a situation where teams are just reluctant to tie up their cap space with an offer sheet (something we saw play out this year with He Who Shall Not Be Mentioned), who was a better player than Vassell to this point and with a much more affordable max available.
Bane didnt get the max (though he got a lot), but he's also simply been better than vassell. better volume scorer, more efficient scorer, better passer, and even a better defender. vassell was billed as a 3 & D with upside but Bane has been better at 3's and at D

. bane had the 2nd highest RPM of all SG's last year after Mitc . i dont think vassell can point to bane as a template at all.
my thought was getting vassell at something like 4/85 or 4/90 would be fine. he wanted 25 per i'd say it would have to come on a 5th year, so something like 5/125 otherwise. obviously with rising cap numbers, those could all be adjusted upward somewhat, but i dont think vassell is seen as this sure thing future all-star around the league.
if vassell really wanted to point at someone to get a better deal it probably would be Herro, who signed 4/130. i know ST hates herro, but herro was more dynamic and effective than vassell thus far, as well. the reason we love vassell is because we can still see the upside. he has more physical tools than herro, but we cant act like he's already put it together
