Mavs: reduce Bayor contract and extend Munson

[MavsGM]

Old Total: $1335

Spend: $300 to reduce Baylor's contract
          $450 to extend Munson's contract


New total: $585

[SpursGM-old]

From the rules:

If you want to purchase a contract extension, the request must be made to me before Sim 12.

Also I think Baylor's reduction had to be before sim 12.

[NetsGM]

I'll let it slide, since I haven't sent out re-signing offers yet.
