Here's Riley after tonight's soccer game - he's got his checklist of who's played what shift, and who's on next. This is mimicing how I do thing - I've got a list of players, their number, what line their on. I then look at that list to see who hasn't played the longest, and pick those for my next line.
Mind you, if I had a full team every time.. it would be a lot easier to get lines setup!
I think I need an app for this...
