Hire Ray Searage? The guy who couldn't get anything out of Gerrit Cole and Tyler Glasnow? Yeah he made 35 year old AJ Burnett good again and turned around low 30s JA Happ, but is that really the kind of pitching coach we want to develop guys like Nate Pearson? Does Pete Walker suck because Marcus Stroman and Aaron Sanchez are uncoachable douches? Does he not get some credit for Sanchez's one outlier good year, or Osuna turning into a star closer fresh out of A+? Romano, Kay, Hatch, Thornton, Borucki all look like young serviceable pitchers, with most of them being fringy prospects to start with, does Pete Walker get no credit in that? What about Dolis looking better in his last couple of appearances after beginning the year looking like he would be outmatched by AAA hitting? MAYBE PETE WALKER FIXED HIM.
The truth is we know nothing about how much impact the major league coaching staff has had on these players, we can see that our manager consistently makes questionable/bad decisions so that's someone I can agree probably has to go. As for windmill Rivera, yeah he's awful at sending runners, but we've seen improvements on defense from Bichette and Biggio after being declared below average defenders in the minors. Not sure who works with the outfielders but that coach has made Teoscar look less terrible and Gurriel go from having the yips to playing a passable LF with few reps. How much is that on the coaching staff and how much is it on the players themselves to improve?
People are making reactionary claims after the huge sample size of 10 games in a shitshow of a season (we're only 4-6 btw lol, after facing good teams like Tampa and Atlanta with the reigning WS champs mixed in there) where the Marlins are currently leading the NL East by a landslide. Everyone needs to calm the f*** down.
