Some subscribe to that theory, I don't happen to. Byes are a bigger pain this year because they end as of week 9 instead of week 10 as in the past and as a result weeks 6 & 7 are really bad because there are six teams off on both those weeks.
Whoa, I didn't notice that!!
I don't put much into the bye weeks either. I usually draft the best player available, regardless of position, and bye weeks, early on that is. In deeper leagues, you may need to pay more attention to it, but in a 10 or 12 man league, you don't need to worry much about them. Ideally you're gonna want your backups to have different bye weeks than your starters, but I wouldn't pass on a good player just because the bye week is the same.
