Yeah this team is rock solid. The only qualm I'd make, and it's a minor one at that, is that you're a little thin on RB's, although you have two competent ones to start for you, and one in Felix Jones that, if he stays healthy, is going to be a PPR monster.
As it's PPR, Jennings and/or Jackson may be boom/bust players for you this year. They're great receivers who rack up yards and TDs, but not so many receptions, and you can't start both of them, so they're kinda wasted space on your bench. If I were in your position, I'd think about shopping one of the two for another RB that can give you a little more depth this year, as Felix and Beanie are injury liabilities, and I'd target a guy like Mendenhall to start.
You're in a good place, well done my friend.
