We did this before in 2009 and 2010. Sure it's not ideal, but you can't win anything if you don't take a few risks here and there.
A risk has to make sense. Dealing Luongo is not in the cards right now. Honestly, having two starting goaltenders is, logically, the best thing a team can do. 50-32 is a great set up for a 1A 1B, riding whoever's hot and making sure there's no rust. If one goes down with injury, you're still set.
A #1 goaltender usually starts 65 games, which leaves 17 to the back up, as well as a couple of games here and there after the #1 has a bad start. Any more games for the #1 and he'll get worn out by the post-season. Imagine having your star player be injured for 17 games with only a third liner to replace his role? Having to play your back up could cause you to go, say.. 7-9-1 instead of 10-5-2 for those games if you had a starter-calibre goaltender in those games, which is 7 points, and in today's NHL, that's about the difference between Calgary/Dallas/Colorado making the playoffs and the Kings not making the playoffs.
It's nice to have a Luongo and Schneider tandem in net, but without some top six help/scoring help, we're not winning anything anytime soon. If we kept Luongo and Schneider this season, I just am not sold we go anywhere, unless Luongo/Schneider can start scoring for us.
For me, the decision to keep or trade Luongo this season is not so easy. We need some scoring.
The team, while not lacking in talented personnel, lack consistency among the players because the Sedins are too one-dimensional. That is the fundamental flaw with this team. With the goaltenders and the defense that we have, we should be playing a stifling defensive system that relies on turnovers and speed to create offense. We should be trapping, considering the lack of calls nowadays. The trap plays to the defense' strengths (big, mobile, good puck-handling) and covers the defense' weakness (speed, ability to break into the offensive zone). The trap also plays into our bottom 9's strengths (gritty, fast, good at causing turnovers, offense off the rush, good positioning) while minimizing the weaknesses (puck-handling, creativity, overall offensive skill). However, the trap isn't great for players like the Sedins, who aren't fast, gritty, or good defensively.
I have thought about what system is perfect for the Sedins, and really, it's the current system right now/ the one in 09-11.. but the system doesn't work because we don't have a fast defenseman who can push the pace. Don't give me "We have Ballard but he sucks." I know we have Ballard, but he sucks, which is why we have the problem in the first place. Trading for Ballard, then keeping Ballard, then not trading Ballard when we could've re-signed Ehrhoff has been Gillis' biggest mistake.
