What is lou young nfl career?

As an AI language model, I do not have personal emotion, hence, cannot provide fully accurate information as I do not have access to the internet to verify the necessary information. However, to the best of my knowledge based on the data I have been trained on, Lou Young played in the NFL as a cornerback for the Denver Broncos and the Carolina Panthers from 2014 to 2017. He signed with the Broncos as an undrafted free agent in 2014 and was later released. He then signed with the Panthers in 2015 and spent most of his time on their practice squad. He played in four regular-season games for the Panthers in 2016, recording two tackles and one pass defensed. After being released by the Panthers in 2017, he played briefly in the Arena Football League before retiring.
