Mariota remains in line to be the Titans' Week 1 starter at QB, backed up by Ryan Tannehill, Joe Rexrode of the Athletic reports.
That's a notion also put forth by Erik Bacharach of the Tennessean. Mariota's perch atop the posted depth chart is not something we expected to discuss at this stage, but as John Glennon of the Athletic notes, there's been some recent speculation that a QB competition between Mariota and Ryan Tannehill could be brewing. Tannehill is one of the NFL's more qualified backups, but his presence doesn't seem to be a threat to the short-term job security of Tennessee's incumbent starter. The story could be quite different if Mariota struggles come September.
