Doesn't every team have 5 relievers who can each throw 160 innings/season?
The point isn't about being able to do that over a season.
The point is that if you can survive a couple of weeks that way, there's no point in having a dedicated guy who can only throw every 5th day (yet who doesn't start). Keep in mind that that inning total is the equivalent to having 4 starters throw 2 innings and 1 throw 3 through an entire turn through the rotation.
Having Berrios, Bassitt, Kikuchi throwing 6 per start, the BP would at most need 27 innings which is the equivalent to everyone throwing 3 innings every 5 days and 3 guys throwing 4 (which again ignores that Gausman and Rodriguez will in fact pitch innings).
In the scenario where the top 3 average 6 and the bottom two average 4, the 8 man bullpen would need to average 2.375 innings per 5 days per pitcher. This is literally where the Jays are today in their worst case scenario (with optionable arms to be able to rotate if necessary). This completely ignores that sooner or later, Gausman is going to find his groove and it'll likely be 4 guys averaging 6 innings and Yariel, who could be on pitch limits (also, the concept of innings limits is stupid and should not be mentioned by intelligent people, because a 3 pitch inning and a 30 pitch inning are not the same thing)
