I don’t get why people keep saying that. 34 for a starting pitcher is not exactly his peak but he seems like he fits the mold of a player who can still pitch very effectively well into his 30s. He is only 1 season removed from arguably the best year in his career. Last year was a down year but he also battled injuries for much of the year and he seemed to be stronger and more effective when he came back from his DL stint in Sept/October. In addition, his xFIP suggests he was better than his mainstream numbers suggest. He’s had seasons worse than last year and bounced back. I get it he’s in his mid-30s, is coming off a down year, and has a lot of miles on his arm. But I wouldn’t quite shut the door on Lester as a TOR pitcher just yet. His fWAR the last four years are 5.6, 5.0, 4.4, and 2.7. I don't mean to get into that common argument about the definition of a TOR pitcher...3.5 WAR would have been good for 18th in baseball last year, so by definition at least a dozen teams would have considered that performance at an ace level. But obviously the Cubs have their sights set higher than most other teams. Obviously we can't expect anyone to repeat a 2015 Arrieta season, but in 2015 the Cubs got a combined 12.3 from Jake/Lester. In 2016, it was 8.2, with what is likely a career year from Hendricks. 2017 was 5.1. This is a long way of saying that in 2015 and 2016 we had at least one, arguably two pitchers that pitched like top 10 pitchers in baseball. While I expect Lester and Hendricks to remain top 25ish pitchers, I think it'd be overly pessimistic to expect top 10 production from them. Quintana has the talent, track level, and appropriate age to get there, so I'm happy to see Zips expects that level of performance.
