Every now and then I get a day mixed up and show up an hour or two before practice is supposed to start. The last two times it has happened — once at the Championship Center on Creighton’s campus and the other at the CHI Health Center Omaha formerly known as, well, lots of different things — I wasn’t the only person in the gym. At the Championship Center, former walk-on point guard Tyler Clement was already dripping in sweat at the tail end of a shooting workout. A few years later at the arena, another walk-on was emerging from the tunnel and heading towards the ball rack to get up extra shots before diving into the playbook of the opponent for that upcoming game.
