The Saints best chance to get out of this contract is this coming offseason. He counts almost 11 million against the cap in 2019 and 2020. His 2019 salary would only be 300k less than Brees. That's a lot of money for a guy that's about to miss his 21st game in the past 3 seasons.
He's only 27 and is a top 5, maybe top 3 LT when healthy. This will be a tough decision for Loomis and Payton.
