I like to look at average draft postition at several sites or even better, get an aggregate list that averages different sites ADP's together. This gives me a good idea where I can expect players to be picked.
I also like to do a lot of mock drafts, here is the site I use.
Looking at other teams message boards can be helpful also. A couple of seasons ago I was on the Denver board where I kept hearing about this 2nd year WR tearing up camp. Drafted Brandon Marshall in the 16th round the year he broke out.
And I keep a magazine in the john to skim through stats.
What I don't like to do is take other peoples advice. I make my own rankings and if they suck they suck, but if they work I'm a genius.
