A Tale of Two (Hypothetical) Rotations

Let’s play a quick game. I’ll list two potential starting rotations, and you tell me which one you’d prefer. First contender:
| Rotation 1 | Proj IP | Proj ERA | Proj WAR |
|---|---|---|---|
| Aaron Nola | 191 | 3.68 | 4.1 |
| Logan Webb | 184 | 3.36 | 4 |
| Nathan Eovaldi | 179 | 3.83 | 3.8 |
| Julio Urías | 159 | 3.82 | 2.7 |
| Sean Manaea | 175 | 3.67 | 3 |
This would be one of the top few rotations in baseball. Nola might be slightly short of the average “top starter on a playoff team,” but it’s close. Webb turned unhittable last year. You can take your pick between Urías and Eovaldi as your third starter; I’m significantly higher on Urías than our Depth Charts projections. Manaea is wildly overqualified as a fifth starter.
Okay, so the bar is pretty high. What about rotation number two?
| Rotation 2 | Proj IP | Proj ERA | Proj WAR |
|---|---|---|---|
| Corbin Burnes | 175 | 3.01 | 5 |
| Blake Snell | 151 | 3.73 | 2.6 |
| Lance McCullers Jr. | 146 | 3.63 | 2.6 |
| Framber Valdez | 188 | 3.79 | 2.9 |
| Alek Manoah | 141 | 3.84 | 2.2 |
Burnes is one of the best five starters in baseball; maybe three teams wouldn’t plug him in atop their rotation, though he has some volume concerns. Snell is a risk as well, but one with a tremendously high ceiling. McCullers and Valdez as your third and fourth starters is an appetizing proposition, and Manoah provides yet more upside. This one projects for less WAR than the first rotation, but in fewer innings; it might tax your bullpen more, but in exchange you’re getting some top-shelf arms. I’d prefer rotation number one, but I think it’s quite close, and I wouldn’t fault you for picking number two.
Is that it? Are we just playing “pick your favorite fantasy team” here at FanGraphs? Don’t rule it out if the lockout keeps going, but no, I picked these groups to illustrate a point. The first group of starters? They were all among the top 15 pitchers in the majors last year at one particular skill: throwing first-pitch strikes. The second group? They finished in the bottom 15.
