Do you think anything that happened between last November and now would have been different if Mo had been fired and Preki given both jobs?
Until MLSE give the same deal to TFC's GM that they give to the Raptors and Leafs GM it doesn't matter who's in the job. In fact, it's probably better to have someone between Preki (or whoever's running the team day-to-day) and the suits at MLSE. Could another GM get more out of MLSE? Maybe, but maybe not. They're no going to spend for another DP this year, and maybe next guy will have to start over and sella player before he gets to sign a DP. Take a good hard look at the company and the way they've run the team so far and take personalities out of it and then consider what would be best.
Besides, it's not going to matter, your worst nightmare is going to come true - TFC is going to make the playoffs by many points and then go deep.
