Brand is 32 years old and next year will most likely be his last most effective one. So I ask you Sixers fan, if the Sixers are not built to win now, then what is the point of keeping Brand?
It's actually quite redundant if you ask me.
And also, the Sixers have many young players that can play the four like Thaddeus Young, Craig Brackins (who has been working his butt off this offseason) and recently drafted Lavoy Allen from Temple.
Next season Brand will be eating away these guys' minutes. Again, I would not have a problem with this if the Sixers were built to win now, but they are not so it is pointless to keep Brand.
If your team is built for the future (like the Sixers) then you want your younger guys (Young, Brackins and Allen) to play with the rest of the younger lineup as much as possible to gain experience and experiment what you have for the future. You do not keep a 32 year old veteran who plays well, but won't be any use because you know you cannot win.
Think of it this way: The Sixers are not built to win now, we know that. But if they start playing the young guys together right now, they will have a boatload of experience four or five years down the road where they will all be at their peaks.
