I can understand the sentiment, but the flack a lot of guys are giving Donnie and Mike on just the rumor of this offer is kind of funny.
The bottom line is so far, Lebron has been rumored to want to play with Bosh and/or Johnson on teams X,Y,Z. He wants to pair up with one of those two. To me that is a fact. Too much smoke. You never hear he wants to team with Wade, Boozer, Amare....
I am gonna preface this with I do not think Johnson is worth the max. But it only matters if Lebron thinks he is worth the max. I can't fault Donnie giving him the max if that extra $2 mil per to Johnson will get LBJ here. If that is what Donnie feels is his best shot he has to take it.
Now personally if Johnson will sign here for a couple mil less that is great. It makes a dream scenario possible if getting Johnson, Lebron-through outright signings- and a guy like Bosh(Curry, Chandler, $3 mil or a S&T with Lee and $3 mil).

Bosh

Johnson
Lebron
Edit: there ia absolutely no way I see Amare coming here in a sign and trade. No way will either party (MikeD or PHX) help each other in a situation like that.
