If Miami signs Karras and a backup quarterback, there's not much left. Maybe in the neighborhood of $8-10 million.Not quite. Most (all?) teams keep a reserve in case they sign someone after season start - say, $5-8mm. Then signing guys like Sanders/Baker. I'm saying $10mm. One avg FA and they're done. That said, there are games to play in designing contracts.
The Dolphins will need to be creative.
