Contracts, salary caps. Why do our favorite teams make some of the moves they do? It's usually the money.

It's time for the Business of Sports with Andrew Brandt.

Welcome back, boys and girls, to another edition of the Business of Sports with Andrew Brand.

Really special edition here, two parts.

Dave Ziren is a writer at the nation.

He has done books all about different things such as the Brazil Olympics.

He has spent time with Colin Kaepernick, and he was a key part of the rally last week

at NFL headquarters about Colin Kaepernick.

I asked him about what that rally meant, would have been

better to do at the teams, what was the impact, and kind of a bigger story than Colin Kaepernick,

the football player, what has been happening around that. Dave spent time with Colin, and very

few people have and talks about his message, maybe even being bigger without Colin speaking.

And then, of course, he's got a new book

project related to this is really going to be interesting. So Dave Ziren, coming up first,

a word from our sponsor, it's Harry's. Harry's is changing the way we shave. It's all about a

great shave at a fair price. There's two guys, Jeff and Andy. These were two guys fed up with

the overpriced razors that you and I deal with so often. They bought their own factory. They had all this blade making experience to make it the highest quality. They offer blades at half the price of the leading five blade razor. They sell directly to you over the internet. They don't deal with any middlemen.

I love it. It gives you a close, comfortable shave. Never have a cut. The fragrant aftershave is

great, not too feminine. Really a nice shave, a nice masculine scent to it. So you can get your

free offer from Harry's. It's a $13 value for free when you sign up you just cover the shipping

and here's what you get you get a weighted ergonomic razor handle you get five precision engineered blades

lubricating strip and turmeric creamer blade you get a rich lathering shave gel and you get this travel blade
