Surround him with shooters you say?
We already need shooters to make our starting lineup work, add Simmons into the mix and major roster moves are needed.
Poeltl would definitely have to go.
I don't think Simmons+DJ+Keldon would work, so DJ would have to go, too. Probably in Simmons trade.
I'd only go for Simmons if it's a reasonable price and we also get Myles Turner. Otherwise it doesn't work.
White-Walker-Keldon-Simmons-Turner with McDermott, Vassell, Landale and another veteran PG (and Forbes, ugh) would be decent.
I'd rather trade Withe than Murray, but Murray doesn't fit with Simmons.
And if we want Turner or a similar shooting big (can't think of anyone right now) we probably lose everyone but Keldon+1 young player.
