Some of you crazies on this board need to do basic math and temper your expectations. Not every player on offense can have a great week every week.
Below is a very timid layout of what stats would make each player have a 'good week.'
Allen-300 yrd and 3 TD
Singletary/Moss- 60+ yards each 2 TDs
Diggs- 100 yards 1 TD at least
Sanders- 80 yards 1 TD
Beasley- 8 catches 80 yards
Knox- 80 yards 1 TD
Davis- 50 yards 1 TD
Do the math unless Allen throws for 400 yards and spreads it out to only the 4 WRs /TE perfectly and doesn't throw to any RBs will each player hit that yardage. Furthermore the team would have to score 6 TDs a game, as well as perfectly spread out again, but then we would be seeing threads of 'Whats up with Bass'
