Based on the current young core, the main guys in Detroit are under club control until 2029. Toronto doesn't even a young core that matches Detroit over the next couple of seasons.
Position players who are under control: Riley Greene, Kerry Carpenter, Colt Keith, Parker Meadows. Better and younger than the Jays position player core. If the Tigers do a solid job adding around them via trades/free agency or if some of their prospects like Max Clark, Kevin McGonigle, Bryce Rainer or Jace Jung make an impact at the big level, they definitely have a positive outlook in the next 5 years.
As for pitching, Tigers have a younger rotation led by Skubal (though he's a FA in 2027), Reese Olson (FA in 2030), and Casey Maze (FA in 2027). Top prospect Jackson Jobe also knocking on the door as well. As for depth arms or back-end of the rotation guys, they have Matt Manning, Alex Faedo, and Keider Montero. One of them might stick as a No 4/5 starter. Short term over the next two seasons, their rotation looks solid if healthy. Just need to add a veteran FA on a short term deal, kind of like what they did with Flaherty.
The big question is can Detroit re-sign Skubal? I believe there were even trade deadline rumours involving him, so maybe he is dangled sometime before 2027. If they can't re-sign him past 2027, they have just a two-year window with him around, so gotta hope some of their positional players can take the next level.
As for Toronto, they have more FA spending room and would be able to lock up their younger stars or top FA's. We'll see what happens with Vladdy, but if Vladdy was in Detroit he likely is traded or becomes a FA. Look at Skubal in Detroit and he likely gets traded before 2027 or walks via free agency. The issue is Toronto currently doesn't have a young solid core or rotation in comparison to Detroit right now. So by time it takes to draft & develop, the Blue Jays are a couple of years behind the Tigers on that front. If the Jays had the Tigers young core, they definitely would have the financial ability to lock up some of the core guys and build around them. Whereas Detroit really needs to take advantage within their 5-year window, or the next two-years with Skubal under control before he becomes a FA.
