So since I am not the most well-versed in the trade-rules-cap-free-agent stuff. Why wouldn't Wash just sign Hump directly? He was a free agent right? What is the benefit to them?
They should be out of cap space by now. Pierce was the MLE signing i believe.
Ok thanks, so the TPE is used by a team who is so close to the cap that they can't absorb the incoming player's salary.
Essentially. To sign a player, you either need to have the cap room to fit his salary or an exception to fit his salary. The Wizards were over the cap, and they used the MLE to sign Pierce. They have the Bi-Annual Exception, but that was too small for Humphries contract ($2 million a year for two years.) So they need a little help. They did, however, get a reported $8.5 million trade exception in the Trevor Ariza to Houston sign-and-trade, so they can use a portion of that to sign Humphries with Boston's help in a sign-and-trade. Boston would get an exception equal to Humphries' salary, expiring one year from the day of the trade (presumably today, but maybe tomorrow or the next depending on Humphries scheduling a physical). They also will have to get at least a protected second-rounder, although standard compensation is at least 1 second rounder that's unprotected.
