Bench Kittle for Tonyan or Knox?

Kittle is running on the side of the field without a helmet. Doesn’t look like he’s close to 100% and he’s never scored a TD on Seattle.

I have Diggs at WR. Playing against Aaron Rodgers and Josh Allen (2qb league PPR)

Would you bench kittle and stream Tonyan or Knox? I’d have to drop Robby Anderson or Tim Patrick…
