I think Simmons fielding percentage of airborn covid globules headed my way is probably somewhat short of Pfizer or Moderna in effectiveness, but may be could give Janssen a run for its money, as well AstraZenica. Definitely I'd give Simmons the starting job over Sputnik Zifivax and Abdala. Neither am i sure i would trust any other middle infielder over him.
And at $10 million he is well below the R&D costs of anything on the market. His problem is that he doesn't scale at all. . It would take more than a decade before new Simmonses might become viable defenders in their own right , and who knows what variants he will be effective against?
So even if he is good enough, there isn't much he can do to stem the tide of the pandemic, and that sets him up for unrealistic expectations.
And as for baseball, keep him around! I personally will be just as disappointed if they let him go early as i would be if they let Buxton go.
