Our other WR's outperformed SEA WR last year and will do so again this year. Roberts is looking better and should have a more successful year, especially when Floyd comes along and frees him up to take slot. Even Doucet trounces SEA WR's let alone Floyd when he comes along.
Peterson is only one aspect of our ST. We had more FG blocks than any team in the league last year and we just drafted a FG blocking stud named Justin Bethel. He's already blocked a FG, an extra pt attempt, and a punt that he returned for a TD this pre-season. He got held twice in a row in the game against the Titans because he was about to block it (those that watched, remember when the kicker took three attempts before it counted? this is why) he's fast as hell as a gunner as well. We have a few other great gunners but I won't bore you with their names and obviously they can block as that is a large aspect of Peterson's success at returns. Ryan Williams will be a force this year and Beanie and Williams together will match just about any stud RB in the league (or at least they were set to before Brown went down). Our OL is better at run blocking, but Brown was a part of that.
Again, we are more complete than SEA, but the argument about where Peyton would be better off doesn't necessarily equate to that because OL is vitally important so I'd still understand the argument that he'd be better off over there. I just don't agree with the complete team statement.
