No, that's a stupid way to do it. Follow a bunch of NFL sources and athletes. You get a constant feed of interesting information. It's like magic.
Just start following a few, and every time there's a retweet of something that interests you, follow that one. I have accumulated about 60 solid NFL ones. (And if one starts to get on your nerves or fill up your feed with stuff you're not interested in, unfollow it.)
There's no privacy issue or "friends." It's just like an RSS feed you're following.
At least follow Schefter and the Denver Post. After a while, there's a glorious feed of constantly moving info. Especially on gameday.
