Flaherty seems like an odd dude. When he calling yesterday's game he had an awkward sidebar with Jeff Nelson about the trivia question where he put Nelson on the spot about looking up the answer on the computer. It was all joking around, but it came off as a little strange to me. Like he was worried that Nelson would get undeserved credit for being smart or something.
And today, as they recognized Brad Ausmus' birthday and showed him in the dugout looking pretty fit for an older guy, Nelson makes a joke about Flaherty's comparative fitness, and maybe JF got offended? He made a point of mentioning that he lifts heavier than Ausmus in the weight room.
I'm sure they're both just having fun and I'm reading into things too much because I'm bored, but I get the impression that Flaherty has a bit of an ego and could be kind of an asshole.
