10 yrs? He did not look like this when he scored those 200s, you can re-watch those highlights. Rohit isn't like inzi/ranatunga who were always chubby even when they were young. If you look at the 2015 wc, Rohit looks as lean as dhawan. He started morphing into current body type since 2018. Metabolism alone doesn't make that much difference in 30s, maybe few hundred calories excess. Lack of discipline after starting family is the bigger issue I think
