Understandable. If Fernandez plays out his arbitration years and is scheduled to make $300M+ like you suggest, I would imagine he's gone on to be a multiple year all-star, maybe a Cy Young and help the Twins make some deep playoff runs... maybe even, gasp, a world series win! Worst case, the Twins can do the same thing the Marlins are doing and trade him to restock the prospect cupboard. As far as your other concern of acquiring someone with arm injuries in the past, man, you're eliminating 25% of current MLB pitchers, and 15% of minor league pitchers alone who have had TJ surgery. I'm not as worried as you about a 23 year old struggling to recover from that surgery. If anything I'm glad he got it at a young age and the odds of him having to get another one in the future is pretty low. In fact, 2-4% of pitchers need a 2nd surgery according to the link below. http://m.mlb.com/pitchsmart/tommy-john-faq/
