Hmmm...I still don't feel like it is a good idea to lock yourself down to one strategy before you walk into the draft room.
I can see the argument and certain situations where these strategies could work, but your pre-draft research time will be better spent refining your own player rankings and staying up-to-date on the news than trying to predict what team you will get if you use a particular strategy. If your knowledge base is good, you can roll with the punches and take advantage of your competitors' mistakes. If you lock yourself into a strategy, you will tend to be afraid to stray from that strategy.
I tend to wait on QBs and TEs until the middle-to-late rounds, and focus on building RB and WR depth in the first 8 rounds (yes, I generally wait until the 8th round or later to take a QB).
