Okay... I've done a fair amount of data reaping from various websites for the past couple of hours and have some very interesting data/statistics to share with you. I'll start at a high level and work my way down.
First and foremost, our Oline back-ups (McQ, Bowie, Bailey and Jeanpierre) were on the field for 1/3 of all offensive snaps (special teams snaps not included). The raw numbers are: Total starter snaps... 3424, Total back-up snaps... 1651.
There were four (4) games when Okung, Unger and Giacomini were all out... weeks 4, 5, 9 and 10. In those four games, the Hawks went 3-1...
... beating the Texans in Houston in OT, 23-20. Marshawn rushed for 98 yards but the Oline gave up 5 sack and 5 TFLs (tackles for loss).
... losing to the Colts at Indianapolis, 28-34. Marshawn rushed for 102 but the Oline gave up 2 sacks and 3 TFLs.
... beating Tampa Bay at home, 27-24. Marshawn rushed for 125 (as did RW) and the Oline did not allow a sack but had 1 TFL.
... beating the Falcons in Atlanta, 33-10. Marshawn rushed for 145 yards and the Oline gave up 1 sack and 5 TFLs.
My conclusion... How many NFL team could go 3-1 without both starting tackles and their center?
And...... could also go 9-1 with their starting LT being out 8.75 games, with their starting RT being out 7.5 games and with their starting center out 3.3 games???
And it's no wonder that many of us here think that Unger did not play well this year. He missed weeks 4 and 5 with an arm injury, he was concussed in week 9 and missed week 10, and he missed week 14 with a pec injury. Personally, I believe that we need to give him a break.
And here's on last stat to consider... during an 8-game stretch (weeks 3 - 10), our back-ups were on the field for a average of 49% of the total offensive snaps.
I believe that Tom Cable should get a lot of praise for what he has done.
For those wanting to look at the raw data, send me a PM with your email addy and I will send you the Excel file that I created. For the Oline starters and back-ups, it includes all of the snaps by player by game and the injuries by player by game.
