I'm a diehard Cubs and Hawk fan. I love the two because there are SO many parallels there:
Both were powerhouses when their respective sport was in its infancy. (Cubs in '00s-'30s and for a while in the '60s - the Hawks in the '20s and '50s).
Then, both were pounded into irrelevancy by a selfish, shortsighted boss (Philip K. Wrigley for the Cubs, Forest Evashevski for the Hawks).
Then, in the '80s, success again coincided for a spell. It dipped in the mid-90s. Both had their finest recent success from around '02 to '09. Once again, both have dipped since that time - and both are destined to rise to unprecedented heights in coming years.
Cubs and Hawks. Peas and carrots.
