Bruh... like you, I've played and coached both, and I can say without a doubt, football is much harder to coach. Football has way more positions on the field of play at one time, 22 v 10, therefore it has WAYYYY more moving parts. On a typical football play, you have at least 4 groups of guys (OL, QB, RBs, and TE/WRs) with VERY different skill sets all doing VERY different jobs... and **** I'm ONLY talking about the offense. This is why you need all those coaches... because all of the groups that are all doing different things within a single play, to come to a singular goal. All 11 have to be on the same page on every play. Man, I ain't even mentioned the 11 on Defense or special teams. In basketball, you do have assistant coaches and they coach different things. I remember Tex Winter was a great assistant, and was the de facto "offensive coordinator" of the Bulls and Lakers under Phil Jackson. Some still coach the Bigs and/or the guards. Nowadays in basketball, all 5 guys are **** near all doing the same things..... because it's moved to a positionless game. Shiddd, nobody even tries to get offensive rebounds anymore, they just shoot and haul *** back down the floor.
If your position is that basketball is a much faster game to coach than football, and the coaches have to think faster, and come up with plays faster, than a football coach, then you would have NO argument here. ****, even if you said that overall, basketball players are better athletes than football players.... I would totally agree. Most basketball players, could probably play a position somewhere on a football field, and do it at a relatively high level, but most football players couldn't crossover and play at that level. Basketball players (IMHO) are the best athletes on earth. But saying basketball is a tougher to coach, when football has a helluva lot more moving parts is ..... wow....
