Not sure how you define a turnstyle in the NFL but I found these stats on our offensive line from last year
Player Sacks Allowed Pressures Allowed TFLA PA %
C Williams 1 13 4 2.75%
T. Biadasz 0 21 2.5 2.28%
Z. Martin 1 19 2.5 2.76%
C. McGovern 1 16 1 5.8%
T. Smith 2 11 0 2.39%
L. Collins 2 17 2 3.74%
T. Steele 2 30 1 5.87%
Steele had the worst PA percentage of any Cowboys lineman including Connor McGovern, who had the 2nd worst. As I have been saying, based on what we saw from Steele last year we cannot say definitively he is ready to replace Collins with certainty. Of course these are just passing stats.
