Year 2 of the Deion Sanders experiment is well underway and a lot has changed in Boulder. Much of that, of course, is due to the transfer portal, but there are a few constants with the 2024 Colorado Buffaloes.

Both Travis Hunter and Shedeur Sanders are back. And so are the patches on both the coach's gear and his team's uniforms. You may already know about why the team has 'L' and 'D' on some jerseys. But why is Deion wearing "JC" on his sleeve?

Those are the initials of former Florida State equipment man Jimmie Callaway and Deion's bond with him runs deep.

Callaway, who died in 2020 at the age of 85 due to heart failure, spent 50 years with Florida State as a volunteer and employee, becoming a mentor to many of the players who came through the program — including Sanders.

Now Deion honors his memory every Saturday when he's on the sidelines. And now you know, too.
