We are no doubt getting too far off subject, but might as well. I am sorry if you do not think the BMI is useful, I do, it is a statistical population tool useful for the vast majority of people to use for comparative purposes to gauge their weight. Again, professional athletes and body builders are not going to fit well in the chart because they are outliers. And, while we are at it, since we are way off subject. What if marathon runners got a five minute break every two miles and a 30 minutes halftime where nearly butt naked women shook their tuukuses and yelled, go Bill/Bob/Mary, go. I contend that many football players are not fit, they are fit for football, fit for lifting or whatever their entertainment specialty is but not fit for life. If the OP wants to get a lower SAC then one of the things he can do is to reduce his weight. You guys are grown ups, it is your hearts pumping through all that mass. Less of you means less of you needs to be fed O2, a heart that does not have to work as hard to pump blood and oxygen is healthier and the body will be more efficient as a result.
And you too should read what I said. Do not bother digging up some more pictures of muscle guys or pro football players. There are probably only ten pro football players who jump in a pool and swim five miles or run a marathon, they are always the exceptional and muti-talented. It is an odd thing that people have come to think distorted bodies are normal with women wishing to be boney thin but few can or should be and men wanting to bulk up but few bulk up with anything but fat so should not. Pro weight lifters and body builders and pro football players are not what a healthy person with good aerobic and general fitness look like, they are distortions for a specific purpose and in some cases a little bizarre. Here you go, note the part where he lost 100 pounds!

I can google up stuff too. So, I will stay where I was, loose some weight, discuss it with a doctor or trainer what a proper weight for your specific body/person would be, concentrate on aerobic fitness with a target heart rate x some interval of time and develop a clear fitness goal and finally do some strength training and the SAC rate will come down.
Weird thing, I started do more weight/strength training, cannot seem to lose my winter fat and am stubbornly clinging to 175 pounds (okay, maybe even a few more than that
) and I want to be back at 165. Yet, I swam my fastest mile the other day and rode my fastest 25 mile bike since I broke my leg 4.5 years ago. I could just tell myself it is muscle and maybe some of it is but then I notice I have a little belly there too, so, no PBJ sandwiches for me for a while. Weight is not everything nor should it be, there is a balance in everything. Come to think of it, I think I will have a PB sandwich right now!
