Again - it's all based on probabilities. Rangers got Yates for like $4M last year and he got Cy Young votes. There was probably a 2%-5% chance he put up the numbers he did last year. Probably a 70% chance he broke down and got hurt. That very well may be the same probabilities for Romano this year. Would you want him for $7.75M for that probability? The Jays may assess that probability, decide that's not worth the risk and determine they either a) want to pay a bit more for higher probability, or take a chance on someone cheaper for the same, or slightly worse probability. If Romano goes on to save 45 games and is a stud this year, you can suggest the Jays assessed that probability incorrectly - and maybe they did, or perhaps they assessed the probability correctly and the Phillies just "hit". Fans will never know the true answer, so their complaints are going to be more hot air. That said, if he pitches well, this certainly is going to come with a s*** ton of bad publicity, whether it's fair or not. AA was lucky because Yates was BALLS for Atlanta, so fans never questioned his decision to let him leave.
(and yes, I suspect Romano has a higher chances of success than Yates did last year)
