Has Jackson Carman did enough to keep the starting position??

[Joelist]

So in two games Carman has given up zero sacks and (I think) 1 pressure? And in those games the OL has as a whole given up 1 sack (arguably Burrow was partly to blame on it) and 1-2 pressures total. And Carman has two flags total (both FS?). Really makes the PFF grades look silly.
