I've never heard anything like that before and couldn't find anything on the Salary Cap FAQ about it. Do you have any sort of link to back up the idea that teams can only have 1 player signed to a maximum length extension?
There's a new set of rules about "designated players." I haven't sorted them out, but this is probably what he's talking about. Coon's question 60.
