Do you know what goes in to pitching development? How many years? The success rate? First of all, teams don't just decide to get better at pitching development. They don't turn coal into gold. Pitching development is completely dependent on the raw material scouting gives them (Alek Manoah!). The seeds are planted in scouting. Read scouting reports on pitchers before they enter milb, they all look to the same stuff: Velo, Delivery, Secondary pitches, Control, Command, Mound demeanor. Many teams have had the same scouts for years, some turn them over every 5 years or so. Across the league teams have been reducing their scouting departments over the last decade. In the Riccardi era the Jays had something like 35 scouts. When AA came aboard he bumped it to over 55 (he came out of scouting himself) and with Shapiro/Atkins they pared it down to about 50, choosing to go with a balance between statistical analysis and traditional scouting. The depth of scouting (# of scouts) doesn't make you better. Sometimes early scouting pans out and sometimes it doesn't. So every 6 years or so, a team may look like it has s***** scouting or poor scouting based on actualy results at the AA level and higher. If it was 2010 to 2016 you would be saying the Astros don't know how to scout pitching. They do. So do the Jays. Oh and you know who has one of the smallest scouting/development departments in mlb? The Astros, around 18 scouts currently. So when you say other teams "have done it in less time" I don't think you're taking in account all the variables. Do we need better arms? Yes, everyone does. Does our dearth of good arms in the pen doesn't mean we need to overhaul pitching development. No.
