The rehab angle is 100% just to clean his name up a little. Anyone who’s actually addicted to something to the point where they actually want to go to rehab wouldn’t be pushing for eligibility in the upcoming season. Imagine if this was any other type of addiction how ridiculous it would look. Your quarterback is hooked on heroin but wants to get sober and has entered a rehab program. All while trying to stay eligible to play college football in a couple of months. It doesn’t work that way.
