Major issues

I'm having a hard time choosing a major. My work will reimburse me 50% of my tuition for a job related major. My original thought was on education because I would love to teach and coach football for a living. I mean how awesome would that be, right! But then I realized 50% of $325 per credit hour is a lot of money at the end of my degree. Not to mention the pay cut I would take to be a teacher.

So what else would I love to do that my work will pay for?

I know that they would pay for degrees in sales, marketing, or business management. I do love the sales and marketing part of my job and I do believe that I'm very good at it. 

So now I'm considering a degree in marketing that my company will pay for half of and then I will right off the entire amount on my taxes. So I would actually make money in the end. Possible enough to pay for a second degree or maybe a masters degree so I can teach marketing or something like that at a community college.

Any suggestions or comments would be greatly appreciated.
