Jack is a poor man's Dick Vitale, however I've grown to tolerate him. Some of his sayings get old quick, but I think he's the best we have now.
Leo drives me nuts. Captain Obvious is a great comparison. I think one night I heard him say "when you get more offensive rebounds, you get more offensive possessions" Thanks bud. He's the worst. I cringe when I see the game is on sportsnet.
Matt is just a homer. He defers to Leo or Jack too often, and it seems he is just told by MLSE to dumb things down for the Canadian Market. I think after 20 years, we don't need Matt's style of broadcasting games.
An easy replacement of Leo would be Sherman. When he's doing the play by play in the preseason, it's much better. I would love to see him over Leo.
In baseball, the later playoff series are broadcasted by one group, North American wide. I was disappointed last year, having the Raptors advance as far as they did, and we still had to listen to our normal broadcast team.
