Christian Kirk or Darius Slayton?

Rosters need to be trimmed to 20, and my roster locks at receiver are presently Moore, Juju, Ridley, McLaurin, Boyd, Higgins, and Edwards.

I was once very high on Kirk, so much so that I traded Godwin for him before Kirk’s rookie year. Oops.

Now my final cut is down to Kirk, versus the upside of Slayton, whom I just took with the final pick in this years Rookie/FA draft. Obviously both would be 6th in the pecking order for the starting lineup (7th after Edwards goes for 12/180/2 in Week One). Thoughts?
