I was just about to say, I feel like we've done this before...then I realized it was a year old, and I had already commented.
I'm going to go with "old MLB" - and by "old" you mean a few decades - becaues that's what I grew up with. As a Cubs fan, the race between Sosa and McGuire was personal, local and extremely exciting. I sat in on more than a few of those home runs at Wrigley Field as a kid.
90's NBA or 2000's NBA? Michael Jordan's era of dominance, or the return of the Lakers as a dynasty, the Heat, Kobi, Lebron, Wade, and dozens of scandals?
