Typically I'd say to throw out the other seasons, but since you so badly don't want to, you do realize what those teams looked like, right? They looked exactly how you want the 2018 team to look- a mix of young players and vets, vying to compete in a division where (as you would say) "anything can happen! sneak in the playoffs and win it all!"
But I'll give the benefit of the doubt and actually throw it out. You can't judge Hahn on what happened from 2013-2016 (but again, if you really want to, those teams were filled with veteran players, so why are you so upset with how he constructed those teams?). Hell, even 2017-now, you can't judge him. These are truly what they said they would be- throw away seasons to grow and develop prospects all the while playing some former decent-good prospects to see if they find a diamond in the rough.
I'm not sure what your guys' point is, but I'm starting to wonder if you and Greg are the same person. Either way, it's super annoying. It's not even an opinion anymore. The fact is, the Sox have tried the veteran/youth mixture already and it hasn't worked. No team goes that route anymore. Give it up.
