On the outside yes and a Slugger/Swarmer hybrid on the attack with the volume of a swarmer and the power, punch selection and accuracy of a slugger. Kovalev is the antithesis of flat footed. He is capable of throwing power punches in combination while up on his toes and moving it's a rare ability for a power puncher to possess especially with heavier guys. That's the most dangerous thing about him his mobility as a puncher and ability to throw with power without having to sit down on his punches.
Sugar Shane vs Ricardo Mayorga . Although too bad this fight took place when both were past their prime , if these 2 would have met up early 2000s in their peaks , it would have truly been a classic . No way in hell Shane stopping that Version of Mayorga .
The best example of this matchup is probably Frazier vs Stander. Pure swarmer vs pure brawler, both operating at a high level. A more modern example would be Pacquiao vs Rios.
Pacquaio-swarmer Margarito-brawler Tho Manny outboxed him using speed and angles and Margo was sticking the jab in Manny's face the first 2 rounds from long range. Juan Diaz-swarmer Popo Freitas-slugger, tho he could box too. Williams-swarmer Margarito-brawler
