1. Height- Moss is 6'4". The next tallest WR on the roster is Roydell Williams at 6'0". One of the things Mike Shanahan really liked about Malcolm Kelly is his height and that's why the Skins wanted Kelly to be out on the field so badly. Jump balls and fades are doable for the taller WRs. With Kelly on IR, you bring in Moss for the height factor and if Moss isn't back in 2011, then you have Kelly or some other FA/draftee who may be able to fill that role. Right now, there's nobody better available to do that.
2. Production- Moss' numbers haven't been that great in 2010 but let's look at the stats anyway. In his 4 games with the Vikings, Moss had 13 catches for 174 yards and 2 TDs. Now let's look at the Redskins. Roydell Williams and Joey Galloway have less catches in 8 games combined (11 catches 184yds, 0TD). Anthony Armstrong (who I like) only has 17 catches (although he's averaging 21.6 yds/catch) and 1 TD. Even in a off year for Moss, he's doing better than most of the Redskins WRs.
3. More opportunities for Cooley and S. Moss- Randy Moss still requires double coverage against many teams, so this opens up more opportunities for Cooley and Santana Moss and the run game for that matter.
4. Would bringing in Moss hurt Armstrong's development? No. You still rotate Armstrong in with Moss. Moss takes plays off on the field, so it makes sense to rotate him in (kind of similar to Haynesworth) and let Armstrong get some snaps.
So yes, I think it only makes sense to take a shot with Moss. What the heck. If worse comes to worse you cut him just like the Vikings did.
