Bob Costas is passionate about every sport he covers except for Sunday Night Football, where he sucks

Everything that [Bob Costas] attends, that's the kind of passion that Bob puts, except for Sunday night football. He sucks at that. He's like, 'hey, America, knock it off with the guns.' And then everyone's like, 'oh, shit, we should probably get rid of our guns.'

The 2016 Cubs are the best team in MLB history and will sweep the World Series

I think this might be the best baseball team in the history of Major League Baseball, and I think that there's no chance that anything bad could happen to them this year. Like, they're going to cruise. I think it's going to be four-game sweep in the World Series.

Bryce Harper is a coward for taking intentional walks instead of swinging at pitch-outs

I actually think that Bryce Harper is a coward for not swinging at any of those pitches. Say what you want about Vlad Guerrero, but the guy would take a cut at a pitch out. My question is, if Harper doesn't like it so much, why does he put a stop to it and just take a running start and just groove one of the meatballs that's thrown outside?

I probably would have had a better long-term NFL career as a tight end

I thought early on that tight end could have been a potential better just long-term situation for my skillset and [the Jaguars] kind of pushed back on that. So I ended up playing quarterback. I had more offers to play tight end outta college than quarterback. I always thought [the skillset was fitting].

Shaving your head and growing a beard is the only move for balding men

Shave it and grow a beard... my thing was, which I held onto it for a while... and I finally got... I found this barber... He goes 'Dude you need to just shave your fucking head.' That's, yeah, I think you're right dude. It's tough. I shave it. It was just, you know, bullied me into shaving my head.

I quietly retired from the NFL and didn't tell anyone.

I did. I heard Hank mention that the other day and I appreciate that Hank, I have not touched a football since January. I quietly, I didn't tell anybody I retired. Probably just didn't tell anyone. So I guess you guys are kind of the first to hear it publicly.
