Jay Bouwmeester has played in 750 NHL games, including 621 uninterrupted. He has never appeared in a playoff game. The Blues are banking — literally banking — that a marriage with Bouwmeester could bolster their chances of getting into the playoffs and finally get the all-star defenseman his first crack in the postseason. Ending a 10-month infatuation with making Bouwmeester the lefthanded-shooting blue-liner they craved in their top pair, the Blues pulled off a stunningly inexpensive trade with the Calgary Flames on Monday, nabbing the NHL’s current “Ironman” for a first-round pick and two prospects. The pickup was the second in three days for the Blues, including Saturday’s acquisition of defenseman Jordan Leopold, so today’s NHL trade deadline (2 p.m. St. Louis time) could be anti-climatic. But the club does have nine defensemen on its roster, meaning it may try to deal from its depth. Bouwmeester, 29, remained in Calgary on Tuesday, but after obtaining his work visa, he’s expected to meet the Blues in St. Louis today and be on the ice Thursday when the club plays in Chicago. Although his name had been mentioned repeatedly in Blues’ circles going back to last season, Bouwmeester said a day after the deal was consummated that he had not caught wind of the interest locally. “You didn’t hear a whole lot,” he said. “Things up here (in Calgary) can get a little crazy. Now the last little while, when it became a reality that I might be moving on, (the Blues) were definitely a team that was pretty attractive.”
