The Cubs are in the bottom half of the league as a collective pitching staff. 21st overall. Its a staff that doesnt strike guys out (27th in k/9), gives up a lot of homeruns (22nd in the league) and relies on weak contact and strong defense to carry it which isnt great when your staff doesnt generate a ton of groundballs.
Its a uniquely Cubs problem that we havent drafted and developed or signed one in years. Even Jon Lester, who is an outstanding big game pitcher and a hall of very good pitcher, was no where near the level of ace that a big time organization like the Cubs should have every year. Look at the Yankees, Max Fried (Cole when healthy), Look at the Mets, Kodai Senga, Look at the Phillies Zach Wheeler, Tigers Tarik Skubal, Dodgers Yamamoto, Astros Hunter Brown, Brewers have Peralta, Misorowski, Woodruff. The only other team even comparable to us in pitching is the Blue Jays but they are a pretender.
The Cubs have Matthew Boyd, a guy on pace to hit his career innings that he hit one time almost 6 years ago and Shota a fly ball pitcher coming off injury. I dont trust either of those guys for a deep playoff run. We have every single reason to be concerned about the Cubs pitching staff and their lack depth and a go to ace.
