If you haven’t already had a consult with an orthopedic sports medicine group, you might seek their opinion. With 3 major league sports in Cleveland there must be a group that caters to their professional athletes. At least for football, torn biceps and pectorals are not uncommon.
Not knowing if there is a surgical potential for the biceps tendon, there may be trainers at the OSU golf team that can do a TPI evaluation and recommend a training program. Certain swing faults can lead to rotator cuff degradation.
I had a partial Achilles tendon tear 40 years ago. Since it was partial, surgery was not recommended and it eventually healed itself. I don’t know if this relevant to your case. Sports medicine has made amazing strides since the first Tommy John elbow case. Experts may have additional options for you.

I have had 1 Achilles surgically repaired and the other rehabbed back to health. I am curious if you waited a while to get the bicep tendon checked out. I remember the surgeon telling me that you can't wait to repair tendons that are completely severed as they will shrink rapidly and make it difficult to repair. But I agree with Don that there has been so much advancement in medicine. I met a guy who tore is Achilles in the 70s and was put in a full leg cast (toe to hip) for months in his recovery. I was in a hard cast for 9 weeks then a walking boot for 3 weeks. Now it seems that people are walking much faster. Heck, Aaron Rodgers was joining Jets practices just months after tearing his.
