If it is three years at 15, then Pierce can go into it expecting to recieve only 30 mil (with the one year lost to lock out)
This changes drastically if you reduce the number.
So the question becomes, does Pierce think he can make 9 million in 2012? 7 million (then 14 per works). 5 million (then 13 per works)
Or does he want all that money now thinking this could be the last year I play in the NBA?
