Fantasy Playoffs RB Handcuff Advice

My league has made several interesting decisions this year which has left me in a unique position. Firstly we have a 4 RB limit for the season due to some hoarding last year. This has left almost every RB handcuff available. Also we are having a 3 week Playoffs which will start week 15 and go through week 17. I am looking to be in these playoffs but my top RBs are Phillip Lindsay and Lesean McCoy while my competition has the likes of McCaffrey, Jones, Elliot and Kamera. Should I chase any good handcuffs in these final weeks or keep depth with safer backups? Ware and Samuels are already owned.

TL;DR

Any good RB handcuffs for the playoffs?
