I just read every post on this subject, and it looks like one of those situations where all I can do is nod in agreement with what most of you are saying.
I've seen some interesting stuff on draft day... and some very unexpected results by the time the season has wrapped-up.
Two years ago, I watched a guy who lives and dies by "Stud RB Theory" wind-up with the #10 pick in a 10-team league. We talked strategy for months prior to the draft and he was unshakable about his RBs. Regardless of where he picked, he was taking the best available RB in the 1st, 2nd and possibly 3rd rounds. So draft day rolls around and I picked 9th and took Travis Henry. He picked 10th (& 11th) and took... ?
Yeah, you guessed it... Harrison and Owens! Needless to say, I jumped all over Moss with the 12th pick (I learned later to avoid panic when it looks like there's a run on a certain position).
The point of the story is this...
With some risky (but well-researched) picks in the middle rounds, this guy was able to "compensate" for taking two WRs with his first two picks (I think he "stole" Shockey in the 6th). And that made all the difference. He went on to win the league against some solid competition.
The following season, I watched a guy draft RBs with 4 of his first 5 picks (and 6 RBs overall). When the draft was over, my only question was how he would fair without a top-notch QB or TE... and only one solid WR. During the regular season, he was stopped... but twice. He moved through the playoffs like a hot knife through butter and took the league with only a half-dozen plays on the waiver wire. In his case, it was just a perfect textbook Stud RB season with no injuries and no need for effort after draft day. (and where's the fun in THAT?!!)
If sticking to a tried-and-true system works for you year-in and year-out, then good for you. I've seen it go both ways.
