At first glance I wasn't sold on this team when I saw Broyles in the flex but with Vereen on your bench I believe this will be a top half team in a 10 team league. The one move I would explore making is trading away Ben Tate to the Foster owner. Foster is still nursing an injury and his owner likely values Tate more highly than you do. If you could use it to upgrade at RB3 or WR3 I would recommend it. 10 team leagues are relatively shallow so any time you can package to get higher tier talent I would.
I agree with the previous posters. Solid team with a really nice bench. Bell will probably be your regular flex by the end of season and I think he's going to have a great year when he returns. WR is the only area I see that could use some tweaking. I haven't quite bought in on Tavon Austin yet as wide receivers rarely blossom in their first year. He should be an electric talent with plenty of upside, but not sure if this is the year he takes off. I like the potential upside of Broyles and Lafell as well, but you could be in trouble if all 3 (Austin, Broyles, Lafell) are at the low end of their projections as none are a safe bet. Using Tate and/or Sudfeld in a deal with a Foster or Gronk owner might not be a bad idea if you can work a trade for a solid/consistent WR3.
Solid team. I see Stafford's pass TDs going up with Bush out of the backfield. Best TE in fantasy, best RB in football, you should have a very solid season. My only hesitation is Johnson, and that's only because he's burned me so badly. If he turns it around, you definitely have a playoff team.
I agree that you should look to improve your WR3. In a 10-team league, there are certainly better options available. I am a fan of Broyles, but I am skeptical of Welker (bad hands), VJax (questionable QB).
I also don't like CJohnson, but he is ok for a RB2 with Vereen and Woodhead to back him up.
