Are all touchdowns worth 6 points, including passing TDs? If so, then you need to bump up quarterbacks.
Your 1st round strategy looks good.
In the 2nd round if QBs get 6 pts for a touchdown, then you have to go with a QB there because the other people at the end will for sure take a top tier QB. Otherwise, go with a top WR.
In the 3rd round, I would go with a top WR over a RB because I don't care for the running backs that are going in the early 3rd round. ADP shows that you would end up with Ryan Mathews with your 3rd round pick. I don't think that is good value. I would much rather have Mike Willams (TB)/ DeSean Jackson.
In the 4th round, I would go with a RB. According to ADP, Felix Jones would still be available in the 4th. So I would be targeting him.
In the 5th round, I would go with either a QB (if you haven't already) or a WR. Target Josh Freeman for QB's (starting to go earlier every single mock I do) and Percy Harvin for WR. You could potentially hold off drafting a QB for another round or two if you like to have a dual QB strategy. I like the Freeman/McNabb this year for that strategy. In which case you might want to look at picking a RB in this round.
Potential team 1-5 (if QBs get 6pts TD)
Potential team 1-5 (if QBs get 4pts TD)
Now the people target might be different than who I am targeting in my drafts. This is just an example. You also have to factor in how bullish your competitors are on certain players and whether or not you want to reach.
