I doubt they would win it all if they made it because only 1 of 12 teams wins it all. so that's an 8% chance all being equal. It might be slightly less for them (perhaps 5% or 6%) because are an inferior team. The best team might have a 12% chance, but I think people overate the difference in chances between the best and worst playoff teams. At the very least, there is a strong possibility that a wildcard team could win a round or two, which is is not the ultimate goal but pretty exciting.
I highly doubt the Tigers will make the playoffs. I just don't want to justify trading talent because they couldn't win the playoffs even if they made it. They should trade veterans if the don't think they can get to the playoffs.
