Jeremy Maclin is lining up at DeSean Jackson's old position at right-side wide receiver during Eagles OTAs. Maclin is the new "Z", with Riley Cooper at "X." Rookie Jordan Matthews was excused to attend an NFLPA event, but has been lining up at slot receiver in a Marques Colston-type role. Maclin probably won't do as much slot work as Jackson did -- D-Jax lined up there on 30 percent of his snaps -- but will do the heavy lifting outside. Maclin is a WR3 fantasy pick with WR2 upside.
