Problem is, those pieces are pretty rare:

-Elite QB play (Jakes a good kid but he's average at best and below average in some areas)
-A gamebreaker at RB (We don't have a guy who could potentially take it to the house on any given play but those are super rare anyway)
-A WR that can take over a game (I think Chase has potential to be this guy in his final year but they don't go to him enough and I believe he is limited by Jake)
