It would have been completely idiotic, if he got a suspension for one or two months, considering he wasn't going to race this year anymore regardless. Anything less than a 6 month suspension, would have made little to no impact, considering he was injured as well on top of this covid-season. Nine months sounds bad and severe, but Jakobsen got a much more severe "suspension".
Personally i feel, considering the context, that it is a warranted sentence. Does the punishment have to be more severe because of the injuries? For the people thinking it shouldn't (and there is something to be said for it), how would you feel if the drunk who ran your kid over, got away with a fine, like any other drunk driver?
I'm all for more severe punishments when it comes to endangering other riders. Especially when a rider knowingly does so.
That said, i'm still waiting for the UCI to take its part of the blame. And for the organizer using those useless (or worse than useless, considering those boardings were not only "not" helping to prevent further injuries, but were probably responsible for causing more injuries, compared to no boardings at all) boardings. Also, the guy/organization that was responsible for checking the safety, should be sued and fired.
