In the event that Howard signed with the Mavs they would have Dirk,Deron,Howard as their core with both Howard and Deron taking less than the max.
The Mavs won't be able to have the mid level until the year after that and they lose all/only young player in Beaubois and they don't own any pick this year.
They also have 44 million guaranteed to Dirk the next 2 years, not going to get more than the room exception 2.5 million.
With the Nets it's going to be Deron, Brooks, S.Williams, Petro, Farmar, draft pick, Howard.
Not exactly a contender there,I don't think Lopez plays on his QO and noone would want to take Petro and Farmar who will opt in to their contracts.
Yeah I know they're a "big market" and so on...
Celtics will be able to keep all of these players:
Pierce 16.8M
Rondo 11M
Bradley 1.6M
Johnson 1.1M
#1 1-1.3M
#1 1-1.3M
#2 .473K
Moore .762K
Howard 20M
Ray 3M
KG 3M
cap hold .5M
=61M
+Green sign to room exception 2.5M
Pietrus accept vet min
Daniels vet min
Stiemsma vet min or other big
Bass sign and traded,give us trade exception and/or pick.
Green could play for a small amount for a year to then sign a big contract.As you can see we have BY FAR the most attractive destination for Howard.
Plus the year after Pierce could retire and get amnestied, make 15M retirement together with Ray and KG and open up cap room to sign Josh Smith or James Harden,and we have Green and Bass exception to use.
The Nets doesn't offer anything close to that, nor the Mavs.
