Can anyone help me with this football (?) jersey?

[DT2003]

I have this jersey in my possession and I have no idea what it is. It appears to be a College Football All-Star jersey, but I am not sure. The front of the jersey says "All Star" (all letters individually stitched) and on the back, it says "McNally" (please tell me it's Johnny). The stars on the shoulders are screened on. The company that made it is POST and it's a Large. Appears to be a cotton/polyster mesh. Can anyone help me? Thank you!
