They're bench players who are sitting more often than not, which is not what we want Martin and Keaschall doing, they should be playing every day either in the majors or AAA. I imagine they will be up sooner than later due to injuries / eventual demotions.
Wade was a borderline outfielder who they should have been patient with in hindsight, but nobody saw him as a MLB-starting player which is why he was only traded for a lousy reliever. Luis Gil was a lottery ticket who took 6 years to become a legitimate starting pitcher in the majors, and Cave did provide positive value for the first couple years of that move. Teams trade 19 year old lottery tickets like him all the time, it's a crapshoot whether they pan out.
Now if you want to delve into the Tyler Mahle and Jorge Lopez trades, you'll have much more of a case against Falvey. They missed on Wade Jr but heck, I would do the Cave-Gil trade again right now if it means we get a 1.5 WAR OF for a couple years in exchange for a longshot guy like Gil who might be good in 2031.
