Boxing Pound-for-Pound Rankings: Gervonta Davis begins his climb up the top 10; Canelo Alvarez slips down

'Tank' plans on only fighting for world titles after his latest destructive knockout

Fourteen months away from the sport did nothing but sharpen the focus of lightweight superstar Gervonta "Tank" Davis.

The 29-year-old Davis, whose career-long layoff included a 44-day prison sentence for violating the terms of his house arrest, looked much more mature inside the ring by patiently shaking off a self-admitted "rusty" start to walk down and finish unbeaten contender Frank Martin with a vicious left cross in Round 8 of their pay-per-view clash last Saturday in Las Vegas. 

There has never been much question about the ability of Davis, or where he might fit in when compared to his pound-for-pound contemporaries. The only thing that has held "Tank" back in the eyes of his critics has been his matchmaking. But after a knockout of Ryan Garcia last April and a thorough dismantling of Martin, Davis is finally starting to make his move within the top 10.
