Trade Question for Keeper League: Ezekiel Elliott for Nick Chubb?

I am in a 4 player keeper league that has been ongoing for over 20 years. I had a great draft, have made good pickups through the season, and am in position to make a run this year. That said, one of my keepers (Zeke), is stuck on a horrible team this year that lost its QB and has an offensive line decimated by injury.

Would you make a straight up trade of Zeke for Chubb? Other keeper caliber RBs are also on contenders so this is the best offer I can come up with. I realize that for the long term, Zeke has a higher upside but this seems to address the need this year.

What do you say...1) Make the trade 2) Don't make the trade or 3) Only make the trade if you can get something else (another player, better draft pick next year, etc.). Thanks.
