"No **** Sherlock"?? Are you serious? I used the, "football and baseball are different" words because those words were the ones chosen by the OP I was responding to...Sherlock.***
Winning in baseball is a LOT easier for us than winning in football. Sure, decisions made by a HC can and do make a difference, but there are a fraction of as many decisions to be made in baseball as compared to football, and what each of the 11 players on your team does on each play can make a HUGE difference in the outcome. More moving parts means more potential points of failure. On any given football play all 11 are in action for the entire play. In baseball it is defensively as little as 2, pitcher & catcher, and is often 4..pitcher, catcher, fielder and 1st baseman. Sometimes it's more, but not all that often.
And in baseball those players mostly just play their position without being told what to do every play, and rarely needing to do anything differently than what they've been doing for years. Sometimes the players need a little more coordination with one another, but the routine plays typically don't even involve most of the players. Offensively you have the batter, and perhaps base-runners, so from 1 to 4 players actually engaged on any given play, with their roles simple, with few options.
Baseball is a game far more tied to pure talent and a little luck than football. A baseball HC has far fewer opportunities within a game to make a "costly wrong decision" than a football coach. A baseball HC has decisions to make within a game. A football coach has exponentially more to make. A baseball HC can be mediocre or worse, yet his team can still win a bunch in spite, because, by and large, baseball players know what to do in every situation without being told. Sure, they sometimes make mistakes, as does everyone...but at our team's level, these kids know. Look at Henderson last year. I love Gary, and think he's a great guy. But his contribution last year was not smart coaching, strategy, etc. It was providing a stable, low-key atmosphere the team needed at that time in the wake of the Cann fiasco. In reality, Henderson blundered a lot last year, but our players were talented enough, lucky enough and self-confident enough to overcome, not just the Cann fallout, but also Henderson's blunders.
While I'd have no problem if you want to claim Henderson helped some with the self-confidence, that doesn't change the fact Henderson made some really bad choices during the season that helped make that miracle run at the end necessary.
A mediocre football HC in the SEC is going to get his *** handed to him week-after-week and get absolutely destroyed by the better teams. A football HC has so much more to work on, and so much more with which to be concerned that comparing the job of a football HC to to that of a baseball HC is silly.
