whether starting a QB-WR from the same team is beneficial or not under different circumstances.
Can you elaborate on that point
Doug Drinen did some work on the subject... dang, it's been over a dozen years now. I feel old. I don't know if the original article is still around, though there's a follow up to it that dealt with QB-RB and WR-WR
here.The gist was that in theory playing a QB and WR from the same team would increase your variance... it would give you bigger swings up and down as that team having a good or bad day passing will affect your team more strongly. If you're the better team that would be a bad thing, since you'd rather both teams have an average day since your average day is better than the opponent's average day.
But if you're the lesser team, you'd rather have a lot of variance. Because if you're both average you lose, and a downswing you still lose against your opponents average day, and whether it's a big loss or a close loss doesn't matter that much. But if it's an upswing, then a big enough upswing can turn a loss into a win. So the underdog in a matchup would rather have a lot of variance in scoring.
He found that in theory, however, the amount you could expect it to help you was small enough as to probably be irrelevant compared to other factors in your decision of which players to start (overall quality of the players, their matchups, etc).
Used to be we had a lot of discussion about these kind of things. We don't see them as much anymore in part because a lot of the questions like this have been investigated already. I suppose there's a whole new crowd of owners though who could benefit from re-examining some of them.
, but MORE drinking for me on the latter
