All Star Game Roster Logic

There are people who want the rosters of the MLB All-Star Game to consist of the hottest players from this season. Their logic is that they want to see the players who are playing the best, and that what matters for this year's game is what the player has done this year. It's not a lifetime achievement award, they argue - what Troy Tulowitzki did last year or the year before shouldn't outweigh the fact that he's playing like a tire fire right now.
