Stewart, Livers for Pritchard, Kornet, Brissett, Svi, and Stevens works (at least on Sunday when Stevens can be traded).
Would have to fill out the bench with players using the TPE. Maybe you even can get Sasser and Umude from Detroit.
Boston probably has to give up 2 1st's along with the 5 players for Stewart, Livers, Sasser, Umude. I'd probably do that, as I like Stewart a lot and believe Sasser could take Pritchard's role (at a much reduced price for the next 4 years).
