Trade Dion Lewis for James Connor?

I have Bell, and received a trade offer for Connor in exchange for Dion Lewis.
My other RBs in addition to Lewis are Mixon, Ajayi, Jamal Williams, Chris Carson, Breida, and Sony Michel. I have plenty of RBs stashed, but do I accept and give up Lewis to solidify Pit RB spot?

I would do it. Conner looked good in the preseason, and who knows how long Bell will hold out. You have plenty of depth at RB, so I would rather lock up the Steelers backfield rather than have Lewis who is in a timeshare. Plus, when would you ever start Lewis over Bell/Conner, Mixon, Williams, or even Ajayi if the matchup is right or Michel if he breaks out.

Thanks! Appreciate the insight.
