From the BP article:

That Tommy John surgery seems all too common is perhaps the best measure of its success. While there is still a failure rate of 10 to 15 percent, most of these happen on younger subjects. It would be more accurate to say that the pitcher fails himself in most cases, rather than the surgery being the problem. Some think the procedure is becoming too common, with younger and younger patients. Others want to have their "prospect" son given the procedure when young so as to avoid it later.

While there are faults, the surgery and the team behind the procedures have made baseball better. One in nine pitchers would not be on the field without it, further diluting the pitching population. Frank Jobe's experiment on a desperate pitcher has become a part of America's game, a routine procedure taken for granted. That alone is pretty amazing.
