The report is certainly plausible. There were reports that both sides were working on a framework for a deal. The numbers make sense to me.
I could see negotiations going something like:
Ainge: Three years, $6m per year. The MLE starts at $5.305m and you're not likely to get more than that.
Bradley's agent: You can sign for four years using the MLE. A full MLE contract would be $22.65m total. Four years, $25m total.
Ainge: What if we make the fourth year unguaranteed?
Bradley's agent: If you really want an unguaranteed fourth year, then let's make it $22.65m guaranteed over the first three years and the final year only $1m guaranteed. My client can't leave guaranteed money on the table.
Ainge: My calculation is that such a contract would start out at about $7.22m and ending at $8.2m. That's a bit higher than I am willing to go per year. Let's talk about a contract next summer.
Bradley's agent: Are you going to trade my client?
Ainge: It's been a pleasure doing business with you.
Bradley's agent:
