Re: Your rooting interest
* whether your rooting interest in the Reds is at all related to the character, effort, and personalities of the individuals who make up the roster
Character, no. Effort and personalities, yes.
* whether, and why, your attraction to the team has fluctuated over the seasons
My first memories of Reds games begin in 1970. I've always watched as many games as possible on tv and listened on the radio in the old days -- even when they were 20 games back in September. I have, however, chosen to boycott going to games and spending money when I felt management wasn't seriously making an effort to win. (Certain years in 80s and 90s)
* whether your affinity for the club declined or picked up (if either) after Griffey and Dunn were traded
Affinity for the club did not change. I was, however, overjoyed when Griffey was traded away (as I was when he was acquired). Same for Casey. Not so much with Donkey.
* whether you believe that Jocketty’s penchant for bringing in players with evident character/leadership assets—Rolen, Cabrera, Ludwick, perhaps Gomes—has played a substantial role in the organization’s competitive upturn over the past few years.
It's played a role. Maybe even a substantial role. Veteran leadership is always needed. But the overwhelming reason for the upturn is the stockpiling of starting pitching and the maturation of young talent from the farm system.
