I don't watch much limited coverage. Unless you draft a ton, it can be difficult to know what's going on. In particular, when a commentator mentions some fringe-playable limited card in one player's hand without specifying what the card does it's difficult to follow everything that's happening in a game. Team events, I make an exception for.
The reason that Team GPs are so much more compelling is that the variance of the game is dramatically reduced. One great player can get outdrawn and make for a unexciting match. Three great players battling for the same match win reduces the chance that a given team loses strictly to variance. The reason that you see Sperling, Rietzl and Williams at the top of Team GP standings consistently is that they're all very good, they play a ton of team limited and they know each other super well. That discipline is just going to pay off more often when only two of the three need to win a round instead of putting all the weight on one player's shoulders.
While it can be fun to watch an unknown player work their way up the standings, I personally enjoy the celebrity aspect of the game more. In particular, watching the narrative of Paul Cheon at San Jose this weekend made the tournament all the more enjoyable. He literally needed the Pork Bun Oath to win the whole tournament to qualify for the Pro Tour next weekend and we got to watch that story unfold round by round.
Outside of being gas to watch, Team GPs drive substantial attendance. 656 teams played in San Jose, which strikes me as reason enough to believe that players would be happy to see more opportunities for team play.
There is a team GP in Detroit this year that falls on my birthday that I'm hoping to hit, but I would like to see at least one more team GP on the schedule. Specifically, I would like to see a constructed Team Grand Prix. If this were to happen I imagine that format would be Team Standard or Team Unified Standard. I would love to see a Team GP that followed the old Worlds team structure where each player played a different constructed format. I really like the way that finding a Legacy player, a Modern player and a Standard player impacts who you want on your team.
If it were your call to make, how would you amend the Team GP schedule?
