I think Edwards is a super interesting case where fit and comfort may play a huge part in his thinking process.
First, his work with Aaron Kromer has to be important. At the beginning of his career under Kromer, Edwards looked like Torrence does now, one of the best young guards in the NFL who was about to cash in. Kromer left, and Edwards's play fell off. Now, he is back to top form under Kromer again.
In LA, for whatever reason, he dealt with injuries and, similar to Mitch Morse had a concussion that ended his season and looked like it could end his career. Here, he has had no issues at all with that. So maybe it's the trainers and staff, or the techniques that Kromer teaches, but he has been able to avoid head injuries.
To me, I am not sure the huge pay day is worth leaving a place that has provided Edwards with so much stability. Additionally, Kromer is unique in his teaching, which isn't replicated around the NFL. I think Edwards is a more likely sign than Connor McGovern or Torrence.
