I'll go with 6 years from now and let me explain. I believe Mac will be around for 2 more years and be fired after going 7-6 in 2019 that is including a bowl loss that's why it's 13 games. After this the new coach will need to bring in better talent because of Mac's inability to bring in talent so he's able to do that in his 1st two classes and we knock on the door in his 3rd year and go 10-2 which gives him his 4th year and we go undeafeded and win a title in his 4th year.
Basically what it comes down to is getting rid of Mac because he wets the bed when he plays legit coaches.
