2. They simply lack talent
While players are getting better, this team simply doesn't have the talent to keep up with Minnesota. If they get healthy and get players like Correa and Buxton going, they will run away with this division.
When you lack talent like the Tigers do, a lot of things have to go right, and a lot has so far. They've stayed relatively healthy (knock on wood), their bullpen has been much better since the start of the season, and the rest of the division is a dumpster fire.
A.J. Hinch is proving once again that he can take a team with little talent and make them interesting. Imagine if he had some star power, Sure, Greene and Tork could reach that some day, but imagine if this roster was more well-rounded. They could be the ones running away with this division, not the Twins.
It would be amazing if the Tigers went on a run this summer and won the AL Central, but it's really hard to see that happening with the lack of quality talent on this roster.
