The Green Bay Packers will begin 2017 without a key defensive starter.

The NFL suspended DL Letroy Guion for the first four games of 2017 after testing positive for PEDs.

Unfortunately for Green Bay, Guion has been in this situation before. He missed three games to open 2015 after violating the substance abuse policy.

The Packers remained patient with him then, and Guion played in all 13 games after serving his suspension. But Green Bay may be running out of patience now.

Guion’s cap hit for this season is over $3.6 million, so the Packers may choose to move on from the nine-year veteran. Rookie Kenny Clark looks like he could develop into a permanent starter, which would help Green Bay quickly move on.

The Packers brought in Guion to help with the loss of B.J. Raji before 2014. He responded with a career year and emerged as a solid free agent pick up.

However, his 2015 and 2016 campaigns were not as successful. He did not flash the pass rush potential that he showed in his first year with the Packers. Nonetheless, Guion still provided much needed depth on a unit that lacked established talent.

But now it could be time to move on. This marks his second suspension in three years, and the Packers could find better uses for the $3.6 million they would save by parting ways.

In all likelihood, the team will stick with their defenseman, unless a free agent pick up is made. Either way, the Packers will need to find additional depth for the first quarter of the season now that they’ll be without a key starter.
