I doubt nothing when it comes to Kromer. He's started rookies in two places with success. Hell, Blythe wasn't all that experienced last year starting just 2 career games before the 16 in 2018. It wouldn't surprise me to see one of the two drafted rookies in the starting lineup. Inexperience is never a good thing but it's really bad if they're unprepared. Kromers lineman seem never to be unprepared. When Whitworth went out last year, Noteboom came in and there was no altering of the playbook. That's preparation (and talent).
