msukc, I think you're right...I like you're top guys in each position: AP, Rivers, V. Jackson & Clark. They all should be in store for great years. But I think you lack a bit of depth, especially at WR & RB.
I would consider Welker and BGE as bottom #2, preferably solid #3 guys. Not to mention, those two players will be fighting for touches as they are on the same team. My biggest concern wouldn't be your studs, but your backups and reserves. Given how the season plays out, I think you'll have a descent team. I would keep my eye on the waiver though...see if you can't add some depth.
Overall, nice work.
