A RB for Mariota

Yo! I’m in a 10 team PPR league. Whats your opinion of a good value for Mariota?

My RB’s are Mark Ingram, DeMarco Murray, Derrick Henry, Doug Martin and Adrian Peterson

My QB is Tyrod Taylor (RIP Rodgers)

I’m pretty deep at RB… I have been offered Mariota for Peterson. With the news about DJ possibly returning, should I do it? Or should I try Doug Martin instead? Or no trade?
