Just because they have some experience doesn't mean they can play as well as last year's line.
Three of them started on last year's line and the fourth would have been a starter on last year's line had he not gotten hurt. These guys aren't just guys who have some experience under their belts. They are, with one exception, the guys who started last year or would have started last year without have gotten injured.
Bisnowaty, 18 starts coming in to this season. Johnson, 16 starts. Rowell, 15 starts. Officer, 10 starts. They aren't just some guys with some experience, they were integral parts of our offensive line the past two seasons.
