Per the Official Site we've lost Steven Harris and Mike Espy:
Espy was set to assume a more prominent role on the Redskins' offense last year when he suffered a knee injury in preseason. He was placed on injured reserve following surgery, ending his season...
Harris had suffered a knee ligament during a 2007 mini-camp practice. He was placed on injured reserve following surgery.
I enjoy watching the discussion here on drafting a WR but don't want to read too heavily into these cuts. I doubt either Mike Espy or Harris were ever threatening the #2 or #3 spot on the roster. If we were set, or opposed to, drafting a WR on the first day of the draft, those plans have probably not changed substantially.
Mike Espy is especially missed. For a guy who was effectively a practice squad overachiever for much of his tenure here, I typed his name on at least 24 different posts.
