Drop Dede for Marquis Brown?

My WRs are:
Keenan Allen
Robert Woods
Alshon Jeffrey
DJ Moore
Dede Westbrook

With Marquise dropping 147 yards a 2 TDs in just 12 snaps and 8 routes I feel like his ceiling is higher. And with the other 4 WRs on my squad, I should shoot for the difference maker. Am I being dumb abandoning Dede so quickly? The foles injury and only 6 targets has me spooked.
