One of the aspects I enjoy about HD is gameplanning. Whether it's true or not, it "feels" like you can make a difference. "Draft your team, set your line-up and let it play out" is SLB. HBD is more complicated but, in the end, you have 9 spots in the order and all are getting 3-4 AB. You may be able to squeeze an extra 15-20 innings from your best pitcher over the course of a season but you're not adding 100. Roster construction, and avoiding injuries(mostly luck), are more important than day to day management.
In HD, you can give a guy a lot of shots or virtually none. You can spread your shots around. You can match your D up to "stop" a top scorer. Same with O to try to exploit a weakness. You can speed it up or slow it down. None of that may matter but it certainly makes you think it should.
I'd like to hear from some of the guys racking up Final Fours on the reg. I have to believe they gameplan. Or I'd like to.
