As much as I hope I'm not one of those losers who brags, "I saw (insert athlete) play back in the day," there are a few moments that were pretty memorable.
Baseball: Saw Bonds hit one into the cove in 2003. I hate that piece of garbage, but it was absolutely amazing.
Saw Joe Randa hit the game winning home run on 2005's opening day in Cincinnati. Opening day in Cincy is always a blast, but that was f'ing nuts. It was pretty much the only highlight from that year.
NCAAF: Too many OSU highlights, but Eddie George's single game rushing record against the Illini was incredible. Jack Nicklaus dotting the I was pretty cool as well.
NFL: As a Bengal fan, there is I want to remember. However, the December 17, 2000 game against the Jags is one for the ages. The game itself was awful with the exception of Peter "Lenscrafters" Warrick running back an 82 yard punt for a TD. What is memorable was it being the 2nd coldest game in Cincy history. Yeah, it sucked.
