I didn't say anything about playoff eras. Again, I'm not basing this off one game and am not a subscriber to the fallacy of small sample "sucks in the playoffs" like many commentators do in all sports.
If you think about, as a starter Burnes was absolutely dominant for 1.5 years. The rest he's just been good. He's gonna get paid off the 1.5 years like he's done it for years. Again, very good top end starter deserving of a big payday. But expecting him to all of a sudden go back to what he did for that 1.5 years should not be expected, but I think he'll get paid like it.
ETA: did a quick glance at Verlander's career, he had way more fluctuation up/down than I would've guessed. He's probably not the best example. But the overall point I'm getting at shouldn't be hard to decipher. For the most part, its extremely rare for mega contracts to pitchers to work out well. I don't think its crazy to say I think Burnes' won't as well. Especially with how small a track record of top top elite he has and that for the last 1.5 years he's just been good, not great. Sure he has another year, maybe he'll go fully Cy Young level again next year and prove me wrong. Hope he does if he's still in MKE
