Meh, season still likely goes off the rails if you have to venture deep into 6-10. These aren't guys you expect to have league average ERAs. If they're under 5.5 you're probably content and under 5 you're very happy. If they're under 4 like Suarez was last year then you're thrilled and as t least somewhat shocked.I'd view it as 1-5 is your rotation's ceiling and 6-10 is the floor, you'd obviously prefer both to be high but a decent 6-10 makes it harder for your season to go off the rails
I think the O's have as good as a group as you could hope for here, but if we need to use them for more than maybe 25 starts we're likely gonna be in trouble. Not definitely in trouble, though, which reflects how much less crappy our guys are than most teams who'd be buried if you need to use that many starters who didn't make your OD rotation.
