No offense intended, but some of you are trying to present yourselves as new school, while simultaneously being a trend or two behind.
Whatever is current/hot/trending changes rapidly. Bill James threw "moneyball" out the window 1.5 years after committing to it. Now you old school types might think that this shows that you shouldnt chase the trends because they are just going to change - so keep it old school - and you would be wrong too.
You gotta change, and you gotta change fast. Or you'll get exploited. For example: People threw high fastball with success, people stopped throwing it, people started throwing it again. Had you threw the high heat all along, you would have gotten wrecked. There was a reason why it went out of style and there was a reason it came back in.
Right now - its sell out literally everything for power. Your nine best sluggers are your team and defense is considered, but thats why you want versatility and redundancy on defense. So if someone goes down (Casas) you can replace him with your new ninth best slugger (whatever position that may be) and because you have so much versatility on D, you can figure it out.
Ideal defensive alignment, OBP chasing, lineup scrutiny. All deemphasized right now. Have your nine best sluggers in, and defense matters to an extent - but be willing to move guys around so you always have your nine best sluggers in. Been this way for 2 years now.
