Using Jason Heyward as a barometer, a player signed 8 years ago, an established MLB hitter, is specious reasoning. First, Curtis Mead is a 22 year old, non-established prospect, and Jason Heyward was 27 years old and had been in the MLB for half a decade. Instead, we should probably look at current Cub prospect development and I think it's pretty clear to see the Cubs prospect development team is generally doing a good job advancing hitters and working with them. They've been able to rebuild PCA's swing entirely; he has added considerable loft and LA to his swing since coming over to the Mets, the Cubs have managed to work with lower level prospects and turn them into quality hitters; Perlaza is adding more impact to his swing (though more from the left side than the right), the Cubs have done great with McGeary and Murray, they've consistently tweaked Caissie's swing (changing his hit box) and they've made huge strides with Amaya (and added considerable LA there since returning from his TJS)...I think it's pretty unfair to blame the current dev team for the failures of established MLB players a decade ago. At this stage, I'm very confident with the Chicago Cubs developmental team when it comes to identifying MiLB players of almost any position, and their ability to work with them. They don't, and can't, bat 1.000, but I'm pretty high on their MiLB system today and their dev team as a whole.
Yeah, Matt Shaw has some Bregman-style to his offensive approach. I never once said "Curtis Mead is the most Alex Bregman kind of guy ever!". I can find similarities in their offensive games while also finding similarities in others. Remember, it's not a 1:1 comparison, and why I hesitate to use them. Clearly this is a sticking point for you; I'll do my best to refrain from them in the future. I also like Matt Shaw! Though I think you get a big hung up on this GB/FB thing; Shaw's far more aggressive at the plate than either Bregman, or Mead, at least using his collegiate career if we want to be comprehensive here and play this out. The K% isn't high, but the reports on him is hyper aggressive. We'll see how that plays out with the Cubs; was it an as aspect of coming from a relatively weaker NCAA conference and just being so good? Is it an issue? Can it be worked on if it is? Time will tell there, it's really hard to nail down. Bregman is among the most discerning hitters in baseball, with well below swing%, first pitch swing% and chase %, so if we want to nit pick comparisons, we can do it at almost every stage. It's why, again, I think comps are not particularly great in general. There's always going to be something different and no two players are identical.
We'll probably just have to leave this here. You clearly have your opinions on Curtis Mead. I think I've made mine clear. You're welcome to your opinion on Mead; the prospect game is rife with opinions and why there's plenty of space for as many evaluators out there on the industry; disagreements are bound to occur. In the end, we'll probably both be wrong on plenty here.
