Well, the upside would be the results he was able to achieve in Buffalo with a line that was completely ravaged by injury. They still finished in the middle of the pack in rushing and that was with mostly back ups. This was accomplished despite M. Lynch having a down year and Fred Jackson receiving the bulk of the load. Also, they have no where near the passing threat the Steelers present on a weekly basis. Hopefully he can help...can't be much worse. Here is a bit of the article I read:
Injuries hit Buffalo hard. By Week 6, Kugler's lineup shared 47 NFL starts. At the end of the year, six offensive linemen were on injured reserve. Five of them started at least one game. Only center Geoff Hangartner started all 16 games at his position.
Not much to work with there and still finishing in the middle of the pack. Hopefully he will help!
