Year after year the price for these rental players is exorbitant and I challenge anyone on this board to give me the name of a trade deadline pick up that proved crucial to a team winning the cup in the year they did it..
1991 Pens get Ron Francis, Ulf Samuelsson, and Grant Jennings from Hartford for John Cullen, Zarley Zalapski, and Jeff Parker. Ron Francis was clearly the key that move the Pens from 3rd to 1st down the stretch of the 90-91 season while then putting up 17 points in 24 games helping the Pens win the Cup.
While not a trade deadline deal, the Dec 1995 trade when the Avs acquired Patrick Roy clearly helped them win the Cup in the 95-96 season.
Rob Blake to the Avs in 2001. Although the Ray Bourque trade the year before was more important, adding Blake sealed the deal.
Mark Recchi to the Canes in 2005.
Guerin to the Pens in 2009. Finished 3rd on the team in scoring in the playoffs.
So there hasn't really been one in almost 10 years. It basically seems like one happens every 5 or so years, so an impact trade deadline deal is overdue.
IMO, the Blues shouldn't do squat. Too much depth is about to jump to the NHL and this team proved, at the start of the season, they can dominate games with this roster (minus Bouwmeester), even though half of it is checking lines. They just need to get back to what they were doing and Schwartz is a huge part of that - largely because, as stated elsewhere, of his away from the puck plays which makes everyone else on the ice with him more effective.
If the Blues could find some way to move Bouwmeester, I think it would help this team more than hurt them. They were the top scoring team in the league defensively until he returned. Now?? Not even top 10 since his return. On top of that, dressing 7 D to "protect" Bouwmeester, because he is hurt? Screw that. Sit his butt.
