Assuming nobody gets hurt, I expect this to be the WR Depth Chart in 2017:
Z- Demornay Pierson - El
Z - Jaevon McQuitty
X- Stanley Morgan, Jr
X - Bryan Reimers
R- JD Spielman
Or
R- Tyjion Lindsey
I also anticipate Lindsey see some snaps out on the boundary, and KJJ may see some time inside at the slot. KJJ actually has a similar skill set to Jordan Westerkamp.
TE - David Englehaupt
TE - Tyler Hoppes
Stoll is a Wildcard because of his knee surgery last August. This Spring will be the first time he actually practices. He's kind of an unknown in the equation. But IMO, he's a Mike McNeil type pass catcher.
Snyder can really run. He has great hands and a wide catch radius, but the coaches aren't really impressed with his aggressiveness or desire to play physical.
