It's not perfect, particularly for relievers, but I'll take a metric using controllable variables over one that's almost entirely opportunity based.
It goes deeper than just the name on the jersey. MN gambled. They moved a high level arm, from a bullpen that needed help, for a reclamation project of sorts with plenty of service time to reap the rewards from said turnaround. Now, a big chunk of that time seems to be gone, and the Twins are paying Rogers to be elite elsewhere. Some posters didn't like the gamble, it's ok.
Sure, if Paddack avoids TJ, comes back, and pitches well then it probably ends up as a W for the Twins. Calling it that to this point though, eh, pass.
