CBS Sports NFL Insider and former Washington Post reporter Jason La Canfora is a Baltimore native and Orioles fan, which you already know if you follow him on Twitter. When the Orioles took two out of three from the Nationals in July, the troll level of La Canfora’s tweets went to 11.

Predictably, La Canfora’s barbs irked some Nationals fans, one of whom did a little digging and discovered that he was once a die-hard Red Sox fan. It’s true, and it really makes his trolling that much more cringe-worthy. Here’s La Canfora explaining how he became a Boston fan in a 2009 interview with Patriots Football Weekly:

“It’s kind of lame, I agree, but I promise I am not a bandwagon jumper. I was sitting out at old Memorial Stadium in Baltimore in the mid-80s with my Roger Clemens jersey on. Sadly, The Rocket’s ascent was a big part of why I was drawn to Red Sox nation, and since he’s left I’ve never been able to stomach the man.”

The self-described non-bandwagon fan was at it again during Monday’s makeup game between the Nationals and Orioles, which resulted in another Baltimore win.

(I blacked out JLC’s non-family friendly hashtag. It rhymes with #Bratitude.)

On Friday, after some preseason football talk with the Junkies on 106.7 The Fan, La Canfora was asked about something far more important: his confusing baseball rooting interests.

“I was an O’s fan for a good period of my life,” he said. “When I was about 12, 13 years old, I fell in love with Ted Williams, and read ‘My Turn At Bat’, the [John] Updike stuff, and everything else, I became a huge Ted Williams fan. And I definitely was a Red Sox fan for a period of my life. I moved back to Baltimore, had kids, started taking them to O’s games, and I was like, this was silly. It was great, I loved it, I was a die-hard Red Sox fan, but I’m back in Baltimore, we’re at Camden Yards all the time, my whole family is O’s fans, my kids are asking about O’s players all the time.”

La Canfora estimates that he was a Red Sox fan for about 20 years before making the switch recently.

“Dude, trust me, it’s weird,” he said. “I detest the Red Sox now.”

That is weird. Much weirder, I’d argue, than rooting for the Nationals and Orioles, but you may disagree.

“I have some fun with it,” La Canfora said of his jabs at the Nationals. “Sometimes you just can’t resist. Sometimes you want to just poke the bear a little bit.”

La Canfora was also asked what he thinks of Bryce Harper.

“I think there’s an awful lot of hype,” La Canfora said. “The perception of him doesn’t match the reality if you just look at the last, I don’t know, 18 months, and it’s unfortunate that so much of it is injury-related. I don’t know. It just seems like there’s a mini Bryce Harper crisis every couple of weeks, and if you’re really a phenom, I don’ t know that that’s the case. There’s no controversy really about Mike Trout. I guess Manny [Machado] had a little bit there. Some of it’s immaturity and these guys come up so young that I think it’s difficult. I mean, dude, I’m from Baltimore. If people are going to pretend that there’s not a little thing between Baltimore and Washington and that D.C. is just so above the fray, then why do people get so [ticked] off when I tweet about the Nats? If it doesn’t matter at all and it’s completely one-sided, then why do people get all up in arms about it?”

Fandom is a funny, funny thing.
