Conner/Adams for Thielen/Johnson/Breida/Ridley

I asked this question yesterday, but the trade offer has changed. I would have to drop 2 players if I accepted. If trade accepted, there is no review period.

This is 12-team, Yahoo Standard, QB/2RB/3WR/TE/FLEX/DEF/K/D

There is a guy who keeps sending me trade offers to give me DJ. I know Conner is the better RB currently, but when Bell comes back, I feel Conner will either get split shares or less.

My Team (2-0, 3rd):
QB: A. Smith, A. Dalton
RB: J. Conner, S. Michel, J. Mixon, K. Johnson, J. Wilkins
WR: J. Jones, D. Adams, G. Tate, D. Funchess, M. Goodwin
TE: O. Howard
DEF: Cleveland
K: D. Bailey
D: J. Watt

Their Team (1-1, 4th):
QB: D. Brees
RB: A. Kamara, D. Johnson, C. Clement, M. Breida, J. White
WR: T. Hilton, A. Thielen, C. Ridley, M. Sanu
TE: A. Hooper, J. Doyle
DEF: Baltimore
K: A. Vinatieri
D: L David, M. Mack
