QB: A- I love Stafford, not a huge Romo fan though. ( even as a backup )
RB: C+ Foster is great obviously but after that all of your RB's are starting the season as backups, they all have great upside though. But you're correct to think that you may need another RB I wouldn't try to make a trade just yet though, scan the WW and wait about a week to see what pans out during the rest of the preseason before making a hasty decision.
WR: A+ I think you did a great job here, you have good starters and your depth is great.
TE: A I like Finley this year and Witten is a good security blanket if Finley doesn't pan out. ( I think he will come back from injury just fine )
D/ST: B- I think you might have reached here taking them with pick 50 in an 8 team league, you might have been able to find a low end RB2 or a good flex RB at that point. That being said, their D/ST is good and will do fine. I do think you should look to drop a D/ST for a good RB as a steal from the WW
K: A+ Akers is good. ( kickers are slightly irrelevant though as long as they don't score 0 points you're fine )
Overall: A- I think you have a very good team here.
