He might be controversial, but he's the kind of no BS kinda guy and I usually always enjoy and agree on his analysis. Bjarne Riis was like this as well though, a lot of oldschoolers were like that, so you should just take it for what it is.. a different era and different view of what it takes to reach peak performance. Also, you should consider the type of rider he was himself - he isn't trying to fatshame anyone or whatever, he's simply speaking about what he sees and how he would go about it himself which obviously was taking it to the absolute extremes at times. No harm done for me personally, but I realize some people think about stuff like that very differently than I do.
Generally though, Rasmussen is scapegoated a lot in Denmark, and you don't hear the stuff about Holm, Worre etc. even though they did the same and they played the same game as everyone else. Again, thats completely fine for me, and if I invested as much as he did, you better believe I'd do the same!
