Teague, who will make his first All-Star appearance, is averaging a career-high in points, assists, rebounds, and steals through the first half of the season and ranks third amongst points guards in Win Shares per 48 Minutes, per Basketball Reference.
Millsap will make his second consecutive All-Star appearance after being voted in by the Eastern Conference coaches last year. Millsap leads the team in points and rebounds and has improved defensively this season, ranking third in the league in Defensive Win Shares, per Basketball Reference.
Horford has rebounded well from last season’s injury and will make his third All-Star appearance, along with the 2010 and 2011 All-Star Games. Horford is shooting 55% from the field on the season, including a league-leading (among forwards and centers) 49.8% from mid-range, per NBA Savant.
Speculation around the league was that the Hawks had an outside chance of getting four All-Stars once the coaches’ votes came in, but it seems that Kyle Korver will not make it this year, unless an injury forces one of the named players to pull out of the game.
