Trade bell?

This week is the last week in the regular season for my league. I am sitting at 6-5 and need to win to make the playoffs. My best player is leveon bell who is on bye this week obviously. Should I think about trading him to ensure I win this week or hold onto him and risk it? I have jordy for bell proposed to me already. I should win this week but if I don't, I would feel horrible for not doing everything I could to make the playoffs.
