I got about 4 hours to pull the trigger here, so any immediate advice is appreciated. Here's the situation: I'm in 3rd place overall, 2nd in points at 6-3 in my league. We start QB, RB, RB, WR, WR, TE, K, DST. No flex. RB and WR get 1 point per 25 yards, with a 3 point bonus at 100. Rushing and receiving TDs are 6 points. 

I have LeSean McCoy, LeGarrette Blount, and John Stewart at RB, and Roddy White, Larry Fitzgerald, Steve Johnson, Antonio Brown, Jerome Simpson, and Mike Williams (TB) at WR. I offered Steve Johnson straight up to the owner who has Chris Johnson, and he countered asking for Steve Johnson plus John Stewart. 

What would you do? If I win this week, I solidify my playoff slot. I don't hate Tennessee's schedule ROS, with Carolina this week, and TB, BUF, and IND left on the schedule, but can I possibly trust CJ?K. Both Steve Johnson and Stewart have outscored him so far this year.
