That, I agree with.
Although in the several crits I did do about 4-5 years ago, my sprint was actually pretty effective, although that's not saying much in a California Cat5 field. I also surprisingly got props from two Cat1s in the LaGrange CA bike club at some of the weekly training rides on the short sprint sections on how my sprint was actually pretty good at the time but big grain of salt on those props as well, as I rarely train my sprint.
