Berglund is a marginal NHL player right now.
No, and this statement makes it relatively obvious that you either: do not watch any other team other than the Blues or you are not aware of which player Berglund is.
Berglund is the #21 with a Bluenote on his chest. Swedish guy. May or may not say "Bork Bork Bork" in the kitchen.
His main weakness is his lack of speed.
Not what I would ascribe his main weakness as (I would say consistency) but I can certainly agree his lack of acceleration hurts, particularly when playing with much faster players such as MPS, Schwartz, Tarasenko, etc.
Add to that the fact that he is rarely physical
Not as much as we would like him to be but he does use the body more often than "rarely"
and has lost his scoring touch, and is not good on faceoffs
Cannot argue that.
and you have the Blues' weakest link.
Have you heard of this Morrow guy?
Not all that much as of late (thankfully)
He should, he is a very effective defensive center. If he could win faceoffs with more consistency he would even be ideal.
he centers our second line, he plays 4 on 4.
Agreed, there should be a better center playing in the second center role as long as the Blues have a glorified second line center playing in the top position.
Berglund does have some skill. He is good with the puck, protects it well, is a good passer.
...This is where you lose me. Berglund is a shooter, his passing is barely passable.
In summation:
Berglund would be a great 3rd line center and a passable 2nd line if he could learn to consistently get the same good results night-to-night. Or he would be fine if the Blues had Joe Thornton on the top line.
I do not foresee the Blues attaining that true #1 center and I do not see the Berglund suddenly figuring out how to play as Angry Berglund every night.
Frankly, if the Canadiens are as serious as some of their fans are for trading Pleks for Stewart and a 3rd the Blues should hop all over that thus giving them a plethora of centers and moving Bergie down to 3rd line where he should be.
Alas I doubt they are and as such the onus is on the Blues to find a good second line center to push Berg down a line.
