Any scenario going forward has risk.
If Skubal is traded for a horde of players, most of the time, the team getting the one star wins the trade.
We could sign him for 6 years and 480 million dollars and he could blow his arm out falling after stepping on a piece of leggo at home, trying to break his fall. Remember, he has had 2 significant arm surgeries, there will be a 3rd more than likely.
The scenario I like is to keep Skubal, get a 3rd baseman, an outfielder, and another starting infielder, and do it by trading a surplus player or 2 such as Lee, Max Anderson, Brecenio, or Layronzo.
Finally, the final scenario is to do little or nothing and standing pat, pinning your hopes on 2027 and beyond. This scenario is the most risk adverse approach, but with very serious risk. This choice is probably more likely than most of us think as the Tigers attendance still is not in the top half of the league, being surpassed by 100 loss Colorado that had one less home date.
Any of these methods have risks. Pick your poison Scott.
