I am curious on how much this impacts his contract offers this coming off season.
Do teams offer fort knox and continue to allow him being a dual threat player, risk all of those hundreds of millions of dollars on a player that could be playing 3/4 of a season, then miss the following one due to a pitching injury.... or well above market value for him being just a position player/dh for the remaining, but at a much lower chance of injury for him and you get the absolute return on your investment.
Of course it all falls to him on what he wants to do. But remember, participation is apart of the grade for the Hall of Fame.
