2) Patrick Mahomes: The Eagles’ obliteration of Kansas City in Super Bowl LIX made it clear that the Chiefs’ offensive line needed some major improvements. So far, the process has taken a little time to sort out, especially after the team’s reported hopes of courting Ravens left tackle Ronnie Stanley ended with Stanley re-signing in Baltimore. The Chiefs slapped the franchise tag on right guard Trey Smith to keep him in house while trading left guard Joe Thuney to Chicago. Kansas City is also signing former 49ers offensive tackle Jaylon Moore, who currently seems the most likely candidate to take over the left tackle job that became such a headache for the Chiefs last season. But here’s the problem for Mahomes: the left side remains a huge uncertainty. Moore has been a backup behind Trent Williams for the last four years in San Francisco, which means there’s no guarantee he can be an effective option. Thuney was the insurance policy the Chiefs turned to late last season, when he assumed left tackle duties with four games left in the regular season, but he’s gone. There’s also likely to be a competition at left guard, where failed tackle Kingsley Suamataia most recently toiled. There’s still plenty of time to figure all this out, but Mahomes might not have any clarity on this until preseason action starts.
