I didn't say washed up... I said he's not a TOR pitcher anymore and he's not... he's a solid 3. You really think a pitcher that's pitching in the league's best pitchers park needs a change of scenery? A guy who doesn't pitch near as well away as he does at said home park... for his whole career.
An argument such as "Verlander blah blah did it so MadBum will too" is awful analysis. So you want to pay the price for an elite TOR ace (under control for just a year) because Verlander did it? Plenty of very good to great pitchers have a handful of dominant years and decline rapidly in their 20s... much more common than a Verlander. Also MadBum has never come close to the level of Verlander in his prime. Everyone remembers MadBum for his playoff performances but his stats even at his best were just very good and not really elite. I'm not gambling ace prices for a guy who hasn't come close to ace status in 2 years, has possible health issues, and has notable home/away splits in the best pitching park in the league. That would be really really dumb.
