it's been a "problem" in baseball, teams tend not to look at getting outside help for hitting and pitching and instead rely on internal resources - and so they should but at some point if something isn't working - like what Akins admitted in his recent press onference to find a "solution" . It will be interesting to see what that is.
The Jays did hire a pitiching resource, David Howell from driveline in 2020 and promoted him to work under Pete Walker - that's promissing
I mean look at this - imagine what they can do for Manoah
