Here are four words that could’ve easily ended up in the script to Groundhog Day: Jon Jones is back. In perhaps the greatest upset in a career where he’s always the betting favorite, Jones is on the verge of putting his latest stretch of trouble behind him. This time he’s returning after popping hot for an anabolic steroid on a test administered a day before he recaptured the light heavyweight title from Daniel Cormier at UFC 214. USADA decided, somewhat arbitrarily (ahem) — if even a little conveniently — that a 15-month suspension was enough.
