I don't play keeper leagues, so it's tough for me to get into that mindset. You are giving up way more value this year, for his first 3 picks next year, You think he'll end up in the bottom 5 this year, but what about if he adds a potential top 5 RB for a couple of bench players?
12 Team League. We start 2 QBs and get .5 PPR, otherwise standard scoring QBs: Stafford, Fitzpatrick, Collins RBs: Charles, Mendenhall, Best, Starks, Carter, Karim WRs: D. Jackson, Marshall, S. Smith, Green, TE: Hernandez, Cook
I would go for it because IMO you are picking up a keeper for next year in Bryant plus his draft picks. Right now Sjax is your Flex guy and looking at your team I think you could play weekly match ups and match his output for most weeks.
Dez could be a keeper, but SJax already is. Looking at your roster, if you kept CJ, SJax, Mathews, Fitz and Jennings, you've got a stud at each of the skill positions. Plus, it could cost you something this year.
