Erik Johnson shocked the hockey world and could have a major impact on the short-term (and long-term) success of the two teams involved (the St. Louis Blues and Colorado Avalanche). The Blues, of course, sent Johnson and Jay McClement to the Avalanche in return for forward Chris Stewart and defenseman Kevin Shattenkirk, while the two clubs also swapped conditional draft picks.
Johnson played just parts of three seasons with the Blues since being the top pick in the 2006 Entry Draft, suiting up in just 203 games with the club (he also missed an entire season due to a knee injury). If that seems like a short period of time for a top pick to spend with a team before getting traded, it is.
Since 1963, twenty-five No. 1 overall picks have been traded at some point in their career, while only eight of them played fewer games with the team that selected them than Johnson before being dealt.
