Slightly different way to look at this class, using 2018 DRA, xwOBA-Against, and WPA/LI. This is assuming Bumgarner/Carrasco/Kershaw/Price/Sale (options), and Morton/Iwakuma (retirement) do not become available on the open market, and also eliminates Miguel Gonzalez/Santana/Tillman due to lack of innings: [pre]Name IP DRA- xwOBA-A WPA/LI Clay Buchholz (34) 98.3 83.5 0.314 2.23 Trevor Cahill (31) 110.0 77.6 0.319 0.95 Bartolo Colon (46) 146.3 142.3 0.380 -1.51 Patrick Corbin (29) 200.0 61.3 0.294 4.61 Marco Estrada (35) 143.7 160.1 0.348 -1.90 Nathan Eovaldi (29) 111.0 72.2 0.298 0.91 Doug Fister (35) 66.0 148.7 0.371 -0.78 Jaime Garcia (32) 82.0 140.1 0.350 -0.98 Gio Gonzalez (33) 171.0 93.2 0.336 0.70 Cole Hamels (35) 190.7 100.2 0.347 -0.04 Jason Hammel (36) 127.0 139.0 0.385 -1.19 J.A.

I'd rather look at 3-year stats for starters, but this is what I could do over lunch. If nothing else, this tells me that retaining Lyles is pretty likely.
