Give chubb for DJ?

*standard dynasty league *
Kinda in a rebuild mode cause of lev bell, but I just got offered DJ for chubb. Am I crazy to be hesitant about this? DJ is noticeable older but has less miles on his legs (only 1 full year) and they did just fire the rb reaper OC McCoy.
My current rbs are : bell, crow, freeman (den), chubb, Rojo, barber
Please lemme know what yall think

Accept it and RUN
