I was thinking this but that wasnt a max contract back then was it.
I think it initialy was supposed to be but the NBA didn't validate it (I don't remember the details). Miami caught a break. Was supposed to be Riles first big signing if I'm not mistaken.
There are many really : Houston, Amare, Rashard Lewis, Joe Johnson...
For me I always felt only the very best should get max contracts, but then again GMs have money to spend. Never understood how 20ish a game could you get the max.
