How well do you know the 49ers quarterback? Last game, Touchdown.....LaMichael James!!!!! won bragging rights with a score of 5.15 out of 6 and currently stands at the top of the leaderboard. Fortunately for the rest of us, it's a new week, and a new opportunity to claim the lead.

The rules are simple. Guess Alex Smith's passing stat line (rush attempts, yards, and TDs will not be counted, unlike last year) for the upcoming game (49ers vs Lions) using the following format in the comments below.

Attempts:
Completions:
Yards:
TDs:
INTs:
Sacks:
Rushing Yards (Optional):
Rushing TDs (Optional):

Feel free to revise your numbers all the way up to game time. I'll use only the most recent guess. If you want to update your numbers, please reply to your original comment with the revised guess.

NEW this round: Although I'm not currently scoring rushing stats (yards and TDs), I'm considering doing something with them at some point. For now, if you'd like to add rushing stats to your guess, please do. I'll highlight the person with the closest rushing predictions in the results column.

Scoring:

The scoring is based on a 6-point system, with each of the following metrics accounting for a point: Attempts, Completion % (calculated from Cmp/Att numbers), Yards, TDs, INTs, and Sacks. It's a bit dry, but for the curious, here is how each of the metrics are scored:

Attempts: 1 - Min(1, Abs(ActualAtt - AttGuessed) / 12)

Completion %: 1 - Min(1, Abs(ActualComp% - (CompGuessed/AttGuessed * 100)) / 15)

Yards: 1 - Min(1, Abs(ActualYards - YardsGuessed) / 100)

TDs: 1 - Min(1, Abs(ActualTDs - TDsGuessed) / 3)

INTs: 1 - Min(1, Abs(ActualINTs - INTsGuessed) / 3)

Sacks: 1 - Min(1, Abs(ActualSacks - SacksGuessed) / 5)

The six scoring categories are added up to produce a composite score. The maximum that can be scored is 6 points; the minimum is 0. I'll keep a running leaderboard throughout the season if there's enough participation, along with posting the weekly results.
