I went to a small rural high school. All of the coaches taught so I had a lot of coaches as teachers. Some of them were excellent teachers. Some were so-so. Some were terrible. I'm pretty sure they would have been about the same, good or bad, even if they didn't coach. Some folks will do a great job at everything they undertake. Some folks will do the minimum at everything they undertake.
I help coach football at a local school after my day job. I only help during football season and it's volunteer work. Being able to see the time/effort the coaches put into their job I've come to believe that head coaches shouldn't have to teach. It's a small school and the coaching stipend for head and assistant coaches is very small. I believe they'd make A LOT more money working those extra hours at a minimum wage job....and have a lot less stress on them. Several of the coaches coach multiple sports...it's crazy the load they carry.
