I say this is a mixture of smokescreens by Bradley's camp and Ainge. Ainge probably did not offer him 7 mil per and that is what Bradley's agent is asking for.
It may sound stupid but in no way is Bradley worth 7/8 mil per season. I think at best he is 5-6 mil per season, and probably no team will offer him that much. I think saying "We offered him 7 mil" is saying "that's the most we will give him, anything equal or less than that, we will match, more than that, you can take him"
