Wiegmann is in his 14th year, yes I said 14th. Our O-line is ancient:
Turley - 9th season
Waters - 8th season (didn't start in 1st year and only started half the season in year 2)
Welbourn - 9th season
McIntosh - 8th season
Wiegmann - 14th season
(although he didn't start the 1st 4 years)
That's some pretty high mileage.
