If Mauer were the regular catcher, sure. As a half-time catcher, not sure his numbers are good enough to be considered an MVP candidate, regardless of how good the team is.
As far as I can tell, and correct me if I'm wrong, the Twins have drafted and signed one player since Joe Mauer who is making more than $6,500,000 a year right now. The drafting has been bad for much longer than five years.
I can't think of anything more ludicrous than questioning Joe Mauer's pitch selection. I can just see some of these people in the '80s talking about how Magic Johnson isn't making the right passes.
If Minnesota Twins, LLC does indeed own the Twins, it is basically guaranteed that it's either to reduce the Pohlad's taxes or to reduce the team's reported revenue. No one has ever made any claim that anyone other than the Pohlads have any control over the club. If Ol' Carl threw Jerry Bell 1% of the team in his will, it's not impacting the team's ability to spend money.
