Good thread. Lots of good comments.
As far as a #6 WR on the active roster, when I pointed out that same thing on another forum, someone pointed out to me that it would be possible if they wanted to do it because of the new 46 man roster. If they don't use the extra spot for a #3 QB, which the Packers obviously won't after cutting Harrell, they could use it for another guy from any position without losing the kind of depth that we're used to seeing with the old 45 man roster plus an emergency QB. The only casualty is the emergency 3rd string QB. If the 46th guy/6th WR plays STs, you're looking good.
As far as the lack of depth on the DL, we have three guys who are fully capable 340 lb 3-4 NTs, and I think every one of the 6 DL has played DE for the Packers at some point last year. If worse comes to worse they could put So'oto at DE. He played 3-4 DE in college, but is undersized for the position in the NFL. He did 35 reps of 225. He's physically stronger than most NFL players, and he showed he can get to the passer against NFL starters and get both sacks and forced fumbles.
