The Marlins have a bright farm and a young rotation. Yelich + Stantion is a great outfield combo (with Ozuna/Marisnick probably getting the call soon). They could be a force to be reckoned with if they continue drafting well and making smart trades and can give Montreal a powerful dynasty, and obviously FAs would come because Loria won't be in the picture
On the other hand the Rays don't have to relocate outside of the state and get a chance to fill the stadium giving them payroll flexibility for the first time ever
