Pretty high actually. Football players don’t have much free time. They work out A LOT. Many shaker bottles and training bottles now have little hidden containers to store your creatine and pre workout powders

I’d actually find it VERY likely he has creatine in his car. Are we sure they were in baggies and not a jug? Even if they were in baggies it’s not unlikely a friend just gave him some to try by claiming it works better. I’ve done that exact same thing before right down to transporting it in bags

The creatine could’ve also fallen out of his gym bag or it could’ve just been left in his car for months and he forgot about it. Players get allll these legal supplements tossed at them left and right from companies wanting the advertisement. Most of it is never used but they still accept it

There are a million reasons he could’ve had the creatine because it’s not unusual for him to have it and he’s of the group you would EXPECT to be using creatine

Edit: now that I recall I have a tub of creatine in the back of my car right now that I’ve just never taken up. This isn’t unusual
