Kershaw actually seems like a good, albeit boring Christian boy, who doesn't have skeletons in the closet.
He married the first girl he ever dated. Doubt he has ever done drugs. Probably has never done roids and never likely will. Probably doesn't cheat on his wife when on the road, even during non-COVID times.
He has a bit of a temper, and gets over-emotional when pitching. That was his enemy in the playoffs for awhile. Then his enemy became his arm simply wearing down.
Roger Clemens was a degenerate. He was also in the Barry Bonds category -- a naturally great player who would have been in the HOF without roids, but just couldn't pass up the temptation to still be dominant in their later years.
