Evans is a big, young, healthy position versatile OL with a lot of games as starter, even in the playoffs.
And you think at his cheap salary he'd clear waivers?
No way. And I guarantee you if the Rams had any thoughts of waiving him, they didn't because they know the same thing. Waive him, lose him... for sure. Just too many teams in line before the Rams in the waiver wire order for him to get bypassed. But... that doesn't mean that at some point they may decide to go with only 9 OL on the 53 and keep another OL on the PS. But it sure won't be Evans.
