Ah, the year 2007: Rihanna and Beyonce were on top of the music charts, and third installments in film franchises ruled the box office--Spider-Man 3, Shrek the Third, and Pirates of the Caribbean: At World's End.
It was also the year the St. Louis Blues had their best draft in the history of the organization. Sure, the 2010 draft has a case, as Vladimir Tarasenko and Jaden Schwartz turned out to be excellent NHL players, but the 2007 draft can't be beat. Unlike a few years later, when it was the worst draft class in Blues history.
The Blues were quite active that year, too. They kicked things off by trading back from nine to 13 with the San Jose Sharks, and the Sharks selected Logan Couture 9th overall. With the 13th pick, the Blues took Lars Eller. Not the flashiest player, Eller has over 1,100 career NHL games, 188 goals, and 424 points; a reliable defensive center any team would be happy to have, and a Stanley Cup Champion with the Washington Capitals.
Then, the Blues made another trade, moving up from 24 to 18 in a deal with the Calgary Flames, who took Mikael Backlund with the 24th pick. At 18th, the Blues selected defenseman Ian Cole, who's had another long NHL career with 908 games and 210 points and two Stanley Cup rings with the Pittsburgh Penguins.
Finally, with their third first-round pick (that was obtained in the Bill Guerin trade earlier that year), the Blues selected David Perron 26th overall. Perron has played nearly 1,200 NHL games, scoring 319 goals and 784 points. Most importantly, of these players, he's the only one who won a Stanley Cup with the team that drafted him; Perron was a key member of that 2019 St. Louis Blues championship team, scoring seven goals (two of them game winners) and 16 points in the playoffs on the way to a Cup victory.
While the Blues may have had drafts that had better name recognition or players more impactful to the franchise as a whole, it's hard to deny that the trio of Eller, Cole, and Perron in a single draft was a homerun. That's what makes 2007 the best draft the organization ever had.
