Amir Johnson resigns with Toronto - 5 yrs @$35 Mill. I think the Raps may have over spent on Amir but he was a good off the bench guy for Toronto last year and if he can get out of foul troubles his game will improve a lot.
And on who would be signed by Miami if they get all three, I can think of Finley for sure and T-Mac. I think T-Mac would come off the bench if it means playing for a ring.
Just a thought too, imagine (because in all likelihood it would not happen), Shaq and Iverson taking minimum contracts loaded with bonuses (in Miami they are lenient on the taxes anyway) then they could possibly have a 5 like: Iverson, D-Wade, Lebron, Bosh, Shaq. With T-Mac and Finley off the bench.
However, Iverson and Bron are ball hogs and all those egos prob would never be able to figure itself out but its just a pipedream.
When it comes to Brown opting out, it is more for job security. There is talk of 2011 having a lockout and if he had opted in, the next season if there was a lockout, he would get zero money, this at least guarantee him money for maybe 3-4 yrs, maybe at a lower rate but still longer. Also if he is loyal to LA, it means more cap space for a team that is always at the luxury tax line
