On the "Injuries" slide, I noted that injuries are not always a good thing.
However, in the case of the Red Wings, the defense needed a shake-up sooner rather than later.
Brendan Smith was playing a lot of time with Kyle Quincey, and it was hurting the team.
Head coach Mike Babcock was forced to juggle his lines when Quincey went down, and this juggling wasn't necessarily good for the team, but it was good to separate Brendan Smith and Kyle Quincey as a pairing.
The need to separate Smith and Quincey on defense comes from Quincey's inability to teach Brendan Smith the nuances of the game.
As a rookie defenseman, Brendan Smith needs to be paired with a more responsible, defensive-minded defenseman.
Quincey is not that defenseman.
It seems like a substantial number of goals that Detroit has allowed this season were from when Quincey and Smith were paired together and on the ice at the same time.
Quincey's defensive abilities (clearing the puck and getting his stick on pucks that are shot or passed) are clearly lacking in proficiency, and this has resulted in a lack of results when he has been paired with Brendan Smith.
