The Detroit Lions are 3-1. They are 2-0 in the division and since they currently hold a tie breaker over the Chicago Bears we can effectively say they are in first place in the NFC North. Since we know a football team is more than the sum of its parts let us take a moment to look at those parts individually.
The most telling stat for the success of the Lions Offensive Line is the fact that QB Matthew Stafford has only been sacked three times. Granted some of that is the scheme they are running, but a lot of credit has to go to a line that has three new starters on it. In particular we should give a lot of praise to Riley Reiff. He has stepped into the LT spot and gone against some of the best NFL pass rushers out there.
We said before the season one the key decisions made this off season could make or break the 2013 campaign for the Lions. That decision was to give the starting RT spot to Jason Fox. He was hurt in game one and has made that decision not as important, but one we must remember was made. Fox has been oft injured in his young career and it might be time to find someone more durable. To be fair Corey Hilliard has been excellent as his replacement.
On the ground this is a team with a respectable running game. Granted having Calvin Johnson at WR gives defenses pause, but the Lions are averaging 3.6 yard a carry and 95.8 rushing yards per game. That is not setting the world on fire but is helping this offense extend drives and not be as pass happy as they have been in recent times. With that being said it seems they are far to quick to get away from the ground game in key situations. That might be because this is still an O line that is not the best at run blocking. So far that is their biggest flaw.
It seems very reasonable to say that the 2013 Lions O line has out performed its expectations, that means 25% f the way through 2013 they have earned a solid A grade.
