Chenal started when we played base in both games. He got about half the Sam snaps in game 1 and nearly 90% of the Sam snaps in game 2. KC mostly played nickel both games. Base 43 was mostly played on obvious run downs.
If the question is, is the Sam a starting position when we play that much nickel, that's a legitimate question. If the question is who's the starting Sam, it's Chenal.
