Even if Spurs offer 4yr/10 million, Butler can most likely make that in 2 years given Barnes (attempted deal in the works) and Bell's deal.
I'd like to sign Butler with or without RJ for 2.365 million per year, he's the best option available for the remainder of the MLE. I just don't think it's realistic. Just like the many people who thought Spurs could sign Outlaw, Miller, Matthews, Morrow, Brewer,Wright for 2.365 million.
It's highly unlikely for Butler to settle for what's left of the MLE, (given Barnes/Bell's deal and with Cleveland being one of the teams having more money and being interested in him). Even if he wanted to settle for the money the Spurs have available, he'd have to choose the Spurs over roughly 10 other teams that would probably be interested in signing him for that amount. It's a step by step progress that you have take into account that makes him very unlikely. (1- Is he willing to take a paycut for 2.365 mil?; 2. If he's willing to take a paycut, is he willing to pick the Spurs over the other multiple teams interested in him for that low price?)
Because of Nachbar and Simmons being the remaining best options for the remainder of the MLE (realistically), resigning Jefferson is a must and is the most realistic and best viable option. (IMO) A 3 yr/24-27 million; or 4 yr/30 million with partial guarantee for the 4th year should be able to get the deal done. Word is from R.C Buford is that they hope to resign him and are working in that direction. The hold up is probably because R.J and his agent are waiting out on a possible more lucrative deal from a desperate team to create leverage against the Spurs initial standing offer. We just have to be patient as this situation unfolds.
