Running Back Riches This Week; Looking To Make A Move

I had a week where all my running backs performed at 20+ points (brown-18.8) so I'd like to strike while the iron is hot. Quick info:

1. 14 team league
2. starting RB spots are 2x RB & 1 WR/TE/RB
3. trades restricted to teams still in contention
4. several teams in the playoffs can be considered weak at running back because of the fact it is a 14 team league
5. Not a PPR league. 6 points for touchdown, 1 point bonus for 20+ yard play, 3 point bonus at 100 yards, 1 point per 10 yards rushed/received (fractions considered)

My question is which RBs should I definately hang on to based on their remaining schedule and which should I try to deal?

Andre Brown
Reggie Bush
Joique Bell
CJ Spiller
Fred Jackson

*I have had remarkable luck starting RBs in the same back field in weeks past so I am not weary of trying it again moving forward based on the matchup

TIA



*ETA per request.

Remaining Schedules:
Andre Brown - @ San Diego, Seattle, @ Detroit, Washington
Reggie Bush/Joique Bell - @ Philly, Baltimore, New York, @ Minnesota
CJ Spiller/Fred Jackson - @ Tampa Bay, @ Jacksonville, Miami, @ New England
