Here is what I see. And I'm sure "most" Coaches do the same thing.

Lemonis loves to play the % and the analytics.

Platooning left and right vs pitching.
Playing the shift defensively, including the times when he doesn't shift until there are 2 strikes on the batter. I question this for 2 instances: 0-2 and 1-2 counts; shifting on an 0-2 or 1-2 count when you are most likely going to pitch to the chase or try to waste a pitch outside, is inviting a batter to go the other way beating the shift.
Some will say well you should pitch em inside 0-2 or 1-2 if you are going to shift. I say 2 things can go wrong pitching inside 0-2 or 1-2. Your pitcher hits the guy, or the guy turns on one and hits it over the shift. I don't like either of those possibilities even if you are trying to get them to hit into the shift. If you are going to shift, shift at beginning of the bat.

As for platooning, I also believe you have to look at a guys approach. If he is prone to a lot of pop out balls to his pull side, platoon him. If he handles the bat well and can hit to all fields, or shouldn't matter which side the pitcher pitches from. Play the best most consistent hitter, period!
