Vincent Smith still doesn't know where he is...
One of the top 10 hits I have ever seen on a football field and one of those ten was my own*.
Seriously. I hardly played in high school and when I finally got into a game in my sophomore year when we were blowing out an opponent I was put in at middle linebacker. This was the Dick Butkus Era and I was all of 5'7 and 145lbs.

I was also a cornerback.

I played a series and even had a tackle then we went on offense and scored on the first play. I was standing on the sidelines when the defense went on the field and a coach noticed I was still standing there and told me to get in pronto.
I was a good 40 yards from the line of scrimmage and I took off. I was small but fast and I never slowed down as I hit the line of scrimmage with a 40 yard head start and hit the QB literally as he took his first step back. I wasn't offsides either.
I hit the QB perfectly literally lifting a guy a good 40 lbs heavier than me off the ground and driving him back a good 5 yards. When he hit the ground the ball popped out and one of my teammates returned it for a TD.
Rudy should have had such a hit.
BTW, the coach (Dwain Painter who coached in the NFL) re-played that play
TEN times during our usual Monday film sessions. He called it the greatest play he had ever seen.
I concur and for anybody asking even 40+ years later I planned the whole thing.
An old HS teammate recently friended me on Facebook and it was literally the first thing he mentioned. It wasn't the highlight of my high school years (surviving them was a really big accomplishment ; ) and I am not doing a "Glory Days" rendition but any time I see a big hit I am reminded of my brief time in the spotlight.
But as I said before I wasn't a very good football player. I was willing and to me that is always enough.
