Firing a head coach mid season really hurts a team more then anything.
- It shows lack of professionalism in the front office as well as lack of logical emotional control
- The former bullet discourages other coaches from taking the job, knowing they could get canned mid-season, increasing the likelihood of getting a lesser, less capable, desperate for a promotion coach since coveted coaches, and up and coming coaches will have offers from more stable front offices
- A new coach mid season isn't going to suddenly turn your team into a playoff contender, making the playoffs. The logical thing to do is stick with em, get a great, very valuable draft pick that will help entice high profile would-be-head-coaches to take the job after releasing the original head coach when the season is over.
