Well worth it for the insurance he provides in the event Elliot gets hurt, has another "off field issue" or both. Elliot averaging 330 touches per year in his 5 year career, and while that shows extreme durability, it also is just a matter of time before he isnt.They take a 3rd now, or they keep him, use him as a #2 HB for two years, and then watch him leave in FA (with the best case scenario being a 4th round comp pick in 2023).
They could trade Pollard, but I'd think it would cost a pretty penny to outweigh his value
