Underdogs often capture the imaginations of fans during the preseason. Those players are always fighting an uphill battle to make an active roster, though.

In Seattle, Jake Bobo quickly became a fan favorite this preseason. He did more than enough to be one of the Seahawks' active wide receivers.

"Jake's flying pretty high right now, he's done great," head coach Pete Carroll told reporters last week. "He hasn't just done well in the few plays in the game. He's done well in practice throughout. ... He's consistent, he's tough, he's really, really smart and savvy. He's been a real factor, and he's gotten behind people too, in both games. I feel so fortunate that we got him outside of the draft."
