I think Poyer is back because we can't replace both safeties with rookies (unless we also grab a FA), but I see our WR1, WR2 potentially both being rookies (even if Diggs returns, has he lost a step or not? If not, then he is still WR1 but we still have 2 new ones that contribute as WR2 and WR 3-4); new DT, new backup C or G, or OT, new RB (Cook backup, perhaps "big" guy).
Will be exciting to see this, it really is "window 2" for Josh. Hopefully this one has trophies in it.
