Pros
Entertaining, vibrant industry makes each day busy and challenging in a positive way. There are so many ways to learn and gain experience. The people are very smart, and diversity (both skill, education and people) is very apparent. They seek out people that are self starters, leaders and passionate. The client roster is impressive, and you work on some highly visible projects. It doesn't hurt that the sports industry will make you the envy of your friends. CEO is willing to spend money to acquire the right people, or business units.
Cons
The "cool factor" of the job (i.e., sports, big events) is that travel is insane, and the work demands a huge amount of hours. Work-life balance suffers. The bigger issue is the shift in focus by leadership from exemplary client service to hard-driving revenue generation. Intra-departmental politicking notably increased during my last months (and anecdotally has gotten worse, from former colleagues reports). Vast majority of senior management is young, so advancement is slow.
