How low could you buy OBJ/Freeman combo

In a 14 man 1/2 PPR.
My team is Stafford, Winston. DJ, Yeldon, Brieda, Lindsay. Diggs, SHepard, Callaway, TY, Watkins.

Im thinking OBJ and Freeman for TY or DIggs/Lindsay. Is that a lot to give up?

No interest in trying to buy freeman atm. That injury is going to probably linger. Why not just target OBJ?

Nice team for a 14 team btw.

Diggs for OBJ?
Thanks. 3-2 at the moment. This is a huge week.
