As a track and field college athlete, I know that practices can make scheduling tough. Sometimes it's hard to squeeze in something like dinner, for instance, because practice goes right up until some other event I have to go to. It's tempting to skip something like a shower and just do that later, so I can have more time.
For me, the situation typically goes like this:
- I have a hard workout which takes longer than usual.
- I need time to stretch, cool down, hydrate, etc.
- I have another commitment later that day/evening, soon after practice, and little time in between. Therefore, I cut out some parts of Step 2.
- I neglect something. For me, it's typically not something like shower; I might skip a cool down run instead. However, I have skipped showers before.
I suspect that this might be an issue for your friend. If his practice is right before your gaming get-togethers, then he could be struggling with not having enough time to shower, change properly, etc. In other words, I suspect time is an issue - not a lack of personal hygiene. He's doing what I've done, and cutting something out of Step 2. That's not that atrocious; the problem is that he's chosen to cut, among other things, showering.
Some things you could do:
Tell your friend that it's okay if they're late because of practice, and that they can take their time. Emphasize that they don't need to rush. For instance:
Hey, [name], I know that you might be having a hard time having practice right before we game. I want to let you know that you shouldn't feel rushed; take your time between going to practice and hanging out with us. Do whatever you need to do - get changed, rehydrate and get a snack, and shower.
Mentioning the shower explicitly, come to think of it, might be a good idea. But you don't have to make it the focus of your suggestion.
- Maybe even move the D&D session back a little to compensate, unless this would adversely affect the rest of the group. Your friend has no control over when his practice ends; is it possible that your schedule is more flexible?
I should justify why I don't think this is an issue of this person choosing to maintain poor personal hygiene. For college athletes, practice and the activities around it are supposed to be as smooth/convenient as possible. Showers, for instance, should be near the locker rooms, and many teams would shower together, especially if the showers are communal. If the friend isn't showering, their teammates would probably point this out before anyone else!
It's possible that your friend is averse to group showers - which is perfectly fine. It might be a cultural issue, or it could simply be personal preference. In that case, they may be even more pressed, because they would then have to shower in their dorms, which could be impractical.
If this is the case, then the problem is again one of time. As I said before, emphasize that they should take the time to ensure that their physical well-being - which should include hygiene - is put first. They might need to reorganize their list of prioritizing in Step 2 - it's as simple as that.
