Not as high on Monroe because from reading the Detroit blogs, he can't play PF. I like centers who can at least be average defensively (on and off ball) and the money he's going to demand isn't worth it to me. I still think he's a fantastic offensive player but his value goes down because he can't play PF.
Well, that's why all these guys are available, right? Guys who make 10-12 million usually have some flaw that keeps them from making max money. They're in between the mid-level guys and max guys.
The question is does having too many of these guys prevent you from ultimately getting the 2 (or even 3 if you look at the Heat) max talent guys you need on a contender? Theoretically you could build a starting 4-5 of all 10-12 million guys and have something close to the Detroit Pistons (Billups, Hamilton, R. Wallace, B. Wallace I would guess all had salaries around that level).
I'd be fine with giving 12/year to someone like Lance Stephenson because he could be the 2.5/3rd banana on a contender. I'm not sure about Hayward because I haven't see him play enough. Monroe is kind of tricky because he's not a good defender and it's not exactly the hardest thing in the world to find big men who can score a little but can't defend.
You can just look at the little demand for Paul Millsap this offseason, or Al Jefferson having a vagabond career. If these guys were so rare they'd never be allowed to leave their original team to begin with.
