Checking in for the first time.  Didn't think I would make it this far.
I have used my flex as follows:
7 RB ($93)      0 times
8 WR ($79)      6 times
4 TE ($21)       3 Times
In fact, there have been FOUR weeks where another WR or TE scored more than my SECOND RB.  I think it is safe to say that I missed on my RB selections this year.  I do not have Foster on my roster.  I have only counted points from 5 of my 7 RBs, including Javon Ringer week 1 and Bernard Scott week 7 (my best week).  The others have been LT2, CJ Spiller, and Best.  Two running backs haven't gotten me a single point, Harrison (oops) and Leon Washington.
For WR, I thought I was done when Clayton went down week 5.  Then TO started his tear, Shipley contributed, the $8 Mike Williams has been solid.  TO was my most expecnsive WR at $19.  I also have Crayton, Garcon, Dez, and Knox.
For TE, I went with the cheap rookie theory.  Gresham, Hernandez, and Gronkowski (NE).  Fasano cost the most at $7.  Think I did pretty well with that group as they have consistently scored and even flexed 3 times.
Carson and Flacco have been a good committee, and Derek Anderson is a tool.
I guess I could have just linked to my team, if anyone cares.

I think I will make it through week 10, and when everyone (Foster owners   

  ) get their full teams back, I will be out week 11.
By the way, 26 players on the roster.
