As Roy said, this isn't a good barometer for Mickey to measure his worth since this seems to be more of an outlier than a rule.
More importantly, Mickey (and/or his agent) seem to be real fools if they think Mickey's situation is anything like McDaniels.
McDaniels knew he was signing with one of the worst teams in NBA history, a team with talent on par with many D-League teams.
While the '15-16 C's aren't going to be remembered in history books, they are a deep team with SIX players ahead of Mickey on the depth chart (Johnson, Lee, Zeller, Sullinger, Olynyk, and Jerbenko).
McDaniels played about 26 mpg in Philly. For Mickey to get minutes like that, he is going to have to pass at least four of them on the depth chart. For Mickey to get minutes at all, he is going to have to pass 2-3.
So this isn't a case of a "if Ainge trades Sully, Mickey can play" scenario. This is a "Ainge needs to trade Sully, someone needs to get hurt, and Mickey will still need to beat out a couple of guys" scenario.
So I don't get this playing hard ball mentality by Mickey and his agent. If Mickey signs a one year deal, there's a far better chance he's out of the league in a year than cashing in on a 3 year 10 million dollar deal.
