I would expect at least 6500 yards of offense for the 2008 season. That's only 626 yards more than last sesaon's 5874 but would puts us at exactly 500 yards a game, which only 6 teams accomplished last year: Tulsa, Texas Tech, Hawaii, Houston, Missouri and Louisville.
I could see the breakdown on the 500 yards a game looking like this:
Passing: 345 yards, 3 TDs
Rushing: 155 yards, 2 TDs
Further, by player, I would expect to see the individual season stats look like this:
Hall: 4350 yards passing, 25 yards rushing (included in the other RBs count), 35 TDs
Other QBs: 150 yards passing, 0 TDs
Unga: 1200 yards rushing, 500 yards receiving, 14 TDs (rush), 5 TDs (rec.)
Vakapuna: 600 yards rushing, 100 yards receiving, 8 TDs (rush), 0 TDs (rec.)
Other RBs: 150 yards rushing, 50 yards receiving, 3 TDs
Collie: 1100 yards receiving, 10 TDs
Reed: 850 yards receiving, 7 TDs
Pitta: 850 yards receiving, 8 TDs
George: 350 yards receiving, 2 TDs
Other WR/TEs: 750 yards receiving, 3 TDs
Things could be even better if we take care of the football next year. Like if we had only 8 fumbles (lost) and 6 interceptions, I don't see how we'd have less than 550 yards a game.
