I personally don't get this issue about the FB's at all. I think they are fine. I get 3 on 1s and 2 on 1s on a good basis. It totally depends on the match-up of course. Sometimes you don't get any, sometimes you get quiet a few.
I might agree with people saying that the AI players on your team could use better ways to extend the FB, but using off ball movement gives you total control about your FB.
Also the opponents Ai doen't execute FB very well most of the time, but everything concerning your team's FB very solid IMO.
