A few random observations:
Dallas's already suspect defense has 2 key members dealing with injuries:
http://scores.espn.go.com/nfl/injuries?team=dal - who just happen to be their DT and MLB. I'm really liking Denard Robinson playing at (his future) home in London at his price point in all formats.
I'm pretty heavy on Dirty Sanchez, mostly due to Chip Kelly's scheme which is pretty darn QB friendly. A slightly step down from Foles with a great matchup playing at home on Monday night at an amazing price point is too good to pass up. Factor in a pro-bowl LG coming back into the lineup, and I think we'll see a more balanced an efficient offense - finally. Perhaps the TE's may be released for more route running as well. However, before automatically stacking Sanchez with Maclin, I want a full game to see what the tendencies might be with the new QB.
On FantasyUp with a more flat QB cost chart, I'm paying a bit more for Ryan and Roethlisberger and see a double Julio and Antonio stack as very exciting, given the matchup and target %.
Kelvin Benjamin playing against Philly's zone heavy defense in a high scoring game looks like a nice play, as well as Justin Hunter playing against Baltimore's depleted secondary. Both players are cheap everywhere, highly targeted with good matchups and will be playing from behind.
As far as TE's, I'm sold on Rivera. Many have pointed out Denver's one Achilles's heel may be covering the TE (see Gronk last week.) Also considering Graham at home vs the 49'ers.
As far as defenses, looking at the Saints, Lions and Cards with good matchups.
