3 quick takeaways from Episode 4 of the Buffalo Bills on HBO's 'Hard Knocks'

The Buffalo Bills were back at it again on HBO's "Hard Knocks."

It was the fourth episode of the NFL's offseason program for the team and there were many behind-the-scenes looks given to fans.

Did you miss the bits from it? Maybe not watch it yet because of roster cuts?

Here are three quick takeaways from this week's episode:

Biometrics

There is a segment early on discussing Chris Hess, who is a biometrics expect with the Bills. The episode details how Hess measures quarterback's movement using 3D motion capture and high speed cameras and more.

A good teaching point from this episode.

Newcomer gets spotlight

Linebacker Jimmy Ciarlo got a lot of attention in this one. The Army product joined the Bills late in camp but eventually made the 53-man roster. He got a lot of love and this episode is why.

Davidson look

Unlike Ciarlo, tight end Zach Davidson was cut... but he could eventually be back. Davidson was the one who punted in the Bills' preseason finale so learning more about him could be interesting.
