In hindsight, it was a complete failure for the front office to anticipate Sale and Paxton making viable contributions to the starting rotation.
Yes, the Sale extension was Dombrowski's goof, but many observers had foresight at the time of the signing, because of recent shoulder woes... remember, the elbow ish came next. But taking a chance on Paxton is on Bloom (and don't say that's all he could spend on, because of Sale's contract).
A lot of us also had foresight when Wacha and Hill came aboard -- not because they weren't good, but because they're weren't good bets not to break down, again, at some point.
It would seem investing in younger arms in their primes would give provide more durability... but how does that explain Jose Berrios' bad status since he joined Toronto? Did he have Covid? Is some longterm Covid effect a subtle reason for disappointing performances this season? Consider: Sale falling apart, ERod's summer, Xander/JD power failures, Kike's injury-prone down year, etc.
