Based on reports from TC, Fisher has faced significant struggles and has been demoted on the depth chart at right tackle. He has been getting beaten consistently by the D has given up too many (virtual) sacks. He has been called for enumerable false starts in back-to-back team drills. Popovich who is not known to be very tolerant demoted Fisher after pulling him out of several drills.
Fisher, who started camp working with the first-team offense, has been relegated to second-team reps reps since the pads came on. Even while playing with the second team, Fisher was called for a couple of false starts and was subbed out, indicating his struggles are persistent. That has relegated him to third team reps.
All of his struggles have to do with loss of quickness, lateral mobility and loss of ability to hold his ground. I'm beginning to think that his regression may be having to do with the knee injury he sustained at Notre Dame. In the 2021 TC, he sustained a knee injury which was reported as "minor." It was a meniscus tear, which the HC encouraged him to play through. He tried, but finally was taken to surgery. And in order to get him back on the field as quickly as possible, since the team was in dire need for his services, they opted to excise rather than repair, saying he would be back within 8 weeks (a repair would have totally ruled out the season). As it turns out, he could not return until 12 1/2 weeks due to setbacks. When you have significant setbacks post meniscus excisions, you are likely to have damaged articular cartilage and setting yourself up for bone on bone.
Be aware that following a meniscus excision (meniscectomy), arthritic changes can initiate as early as 2 to 5 years [perfect timing for Fisher's problems] after an arthroscopic partial meniscectomy. The risk can be even higher for athletes who have a high BMI and heavily rely on their knees as would an offensive tackle.
