Monfils, currently playing at the season-opening Qatar Open, hit a career-high ranking of No. 6 back in 2016, then tumbled down to No. 46 after an uneven 2017 season. His late-blooming career is not one that fits into any obvious patterns, and there is no telling how the 31-year-old will fare this year. For now just be grateful for a fresh season: Tennis is finally back, and so too are its most electric entertainers.
