Though I don't think Sheed is coming back and though I don't particularly want him to, let's pretend he does come back.
Obviously, we become overloaded at the 4/5 position once Perk comes back, as there's no way we're finding minutes for KG, JO, BBD, Sheed, and Perk. And obviously we'd be weak at the 2/3 spots with nothing but the minimum to work with.
Which got me thinking, if Sheed does come back, what could we get by trading Perk and/or BBD? Conceivably we could trade both if we signed someone like Brown, Ratliff, Thomas (leaving us with KG, JO, Wallace, and 4th big). What's more, might Perk and/or BBD net us more at the 2/3 spot than Sheed's contract? Both have reasonable contracts, are fairly young, are expiring after this year, and would give their new team their Bird rights. Moreover, BBD doesn't look to be our starter of the future at the 4 and many have wondered if Perk has priced himself out of what Danny's willing to pay.
I'd still prefer for Sheed to stay retired and to trade his exception. However, there might be other ways to do this if by some small chance he comes back.
