One thing to consider is balancing return yardage with your other league settings. If you've got a fairly touchdown-heavy league, then awarding a lot of return yardage points may help out those who don't draft well, imo. I've been in a league where folks who I knew where less than knowledgeable often prevailed over seasoned fantasy veterans because the former would pick up a good kick returner after the draft and beat the seasoned veterans whose studs just didn't happen to score touchdowns that week. In a yardage heavy league, that effect is somewhat minimized but it still happens. You know something is wrong when the team starting Joshua Cribbs beats the team starting LaDainian Tomlinson.
The object is obviously to reward slightly
the astute managers who draft players who also return kicks, without giving someone a clear advantage to defeat the rest of the league. In my experience, 1 point per 25 return yards or 30 yards is still too generous. Managers should seriously consider giving only
1 point per 40 return yards at most.
