Parker or Sheppard for FLEX start?

My opponent this week dropped Parker and I picked him up so I really want to beat him with Parker in my lineup. Engram is my tight end so that would be two starters on the Giants if I play Sheppard, who I think has a better matchup…any help? Thanks!

Did you end up playing Shepard?

I did! 19.7 points, I’m happy
