Thinking up some ideas..?

I traded McNabb for a 4th pick (first round) in my fantasy league which is a keeper/dynasty league. I really don't care for McNabb so meh...lol. I currently have 3 first round draft picks, 4th, 7th, and 15th (out of 16 teams). The team I inherited isn't exactly great. I have Bulger and I'm thinking about picking up Shaun Hill...and platooning with these two. My only rb's are Fred Taylor, earnest Graham who idnd't have a good year, and Rashard Mendenhall. I want to add Moreno or Beanie. I know I need a qb but I was thinking about just ping on Stafford and Sanchez and wait until next year to try and get McCoy or Bradford. Possibly even Tebow. I'm also looking at trade opportunities (Rodgers,Quinn and a player, and another decent QB who I can't remember) but this came to mind. What do you think about ping up Stafford and Sanchez to try and get Bradford,McCoy or Tebow?
