I was a Chiefs fan starting in 1990 with DeBerg at QB. Defense and STs were really good and fun to watch. That being said, defense always sucked going against Buffalo in the playoffs. Offense was fun at times and very frustrating at times. I remember sitting there in shock and disappointment after the Chiefs went to San Diego in the '92 playoffs and got shut out.
Then the Chiefs went after Montana that offseason. That was such a breath of fresh air. Montana had a hard time staying healthy that first year (and probably 2nd, as well - can't remember for sure) but when he played, he was money. One of my fondest memories was that game at Houston in the playoffs. Montana was so clutch, it was a pleasure to watch. Even after getting beaten up for most of the game, he came through when it counted. Marcus Allen, as well. Those 2 were key FAs that helped turn the team from a WC team to an actual SB contender.
