no it isn't. that is talent. you cant teach hitters to have a good batting eye. you either have it or you don't, it cant be taught.
i have pointed out all the things in his swing and asked if you wanted the cubs young hitters taught to do that. no one has answered yes. he was a great hitter and put up great numbers because he was talented. not because he had great fundamentals. and now you are defending manny with his lack of contact as being a good fundamental hitter? what part of being a poor contact hitter is great fundamentals?
You can't teach a player to recognize pitches? Um... ok. As for contact, I didn't say he had poor contact. I said he didn't have great contact. Manny's contact was 80.5% while his swing% was 44.7%. Fangraphs has stats on 653 players in terms of plate discipline. 80.5% puts Manny at 348th out of 653 or roughly average. If you want to break this up even further, Manny's z-contact was 87.0% of balls in the strike zone he made contact with. His swinging strike% is 8.4% or 302 out of 653.
I should also clarify, I said vlad had elite contact and what I should have said he was elite at putting the ball into play vs K's/BB's. Vlad's actual contact% was 80.7%. The biggest difference between him and Manny was that his swing% was 59.1%. At 44.7% swing% that means Manny took a lot of pitches. Yes, I want him teaching young hitters this. It's frankly one of the biggest problems I have with Castro. If you make a pitcher work a count to 5-6 pitches over your 4 appearances a game that drives starters out of games and gets into the bullpen where there are often inferior pitchers. Of the 44.7% of swings Manny took, 69.5% of them were in the zone.
Either way, there's nothing that suggests Manny had large holes in his swing. The data suggests a patient hitter with average contact and elite power. The data suggests that he waited for pitches in the zone that he could hit and then drove them. And if he didn't get them, he'd often walk and was good enough at fouling off pitches that he didn't get killed by strikeouts. Learning what pitches a pitcher has and which you can handle is a fundamental aspect of the game. Manny wasn't like Vlad in that he took a swing at nearly 60% of pitches and was able to put them in play because of his talent. Manny worked a count and took swings at pitches in the zone most of the time.
If you don't think that's teachable then I don't know that there's anything more to discuss. I'll just point to the maturation of Rizzo. The last 2 years he took a swing at 38.5% and 30% of pitches outside the zone. This year he's down to 24.3%. And you can tell because his walk total is up 6.5% and his K's are down 2.8%. Like wise, Rizzo's on base is up 73 points.
