Sure.
There are 40 starting pitchers listed as available free agents on MLBTR.
Now, some of them, notably Brett Anderson, Drew Smyly, Merrill Kelly, Jimmy Nelson, Corey Kluber, Tyson Ross, Rich Hill, and Michael Wacha I will say are less likely to throw 180 IP than Eovaldi. Others (Alex Wood, Garrett Richards, Mike Minor) are close. So that's 29 right there. (28 if you do not want to include Martin Perez, whose already here and likely to be back.) A few others have team options, but none of them look likely to be picked up.
But then we could also see a wave of pitchers non-tendered. And another set of pitchers readily available in trade. The number could easily reach 40.
As for "good", my premise is based on IP solely. Anything beyond that is debatable, but Eovaldi and his 86 ERA+ since 2018 does lower any bar you want to set...
