Even though every major league team gives each player a physical before the season starts (which includes an eye exam), poor David thinks it would be a good idea to see if his vision is the reason why his skills are deteriorating in his 30’s.
Is it because he is recovering from the post steroid symdrome? Maybe. He also could just be getting older, and because scumbags like Barry Bonds, and Roger Clemens, it has tainted baseball fans to thinking people still produce in their 30’s. If natural, it is very rare to be productive in your late 30’s.
