You're forgetting some intended Dodger pen pieces, including Blake Trienen, Tommy Kahnle, and Daniel Hudson. Mitch White probably if not for Buehler's injury.
Your waiver wires aren't there without IL stints to the above.
Teams serious about their pen shouldnt start the season with half or more coming from waiver pickups and MiLB free agents. Or at the least need to be better at picking identifying those guys than we've been.
In any case, as I said at the time...didn't like the Rogers trade, and I don't think it's just an unfortunate accident that it's turned out badly so far.
I bet if you could get Falvine to discuss privately they'd admit it was a mistake.
