Pretty cool, right? I'm not an NFL scout by trade (sorry if there was any confusion or I misled you in any way), but this 2011 video of Monmouth University's Dan Sullivan seems very impressive! Now, it's possible that, in college weight rooms all over the country, there are just tons of jacked dudes high jumping over shit left and right like they're Luigi in Super Mario 2, but as I mentioned before, I am not an NFL scout and do not have too much insight into the behind-the-scenes of college athletics.
Shout-out to Dan Sullivan for showing that with determination and perseverance the human spirit can really accomplish anything, or at least jump really high.
