As an A's fan, I was thrilled when the Angels traded for Wells. In 3 of the last 5 years he has had a below average OPS+ (85, 86, and 83). The 2 years where he was above average it wasn't anything near justifying the contract that he is receiving (122 and 125).
The Napoli for Wells trade was laughable. It isn't often that a team gets a worse player at a higher salary in a trade.
