Miller's not always that great at it. He's been great the first two games, and he was great at it last October and November, but his effectiveness does take a dip.
I'm not saying Ferraro is better, but the Miller apologists act like he is not replaceable.
I think the skaters in general are given too much credit for the PK. There are moments, such as Z's 5v3 PK against the Pens in the finals, where we see a skater step up and dominate the PK, but it's often the goalies who determine the success of it. If the goalies are rolling, shockingly, so is the PK. The past few years, our goalie tandems have evened out to be pretty average...and so has our PK every year.
I think Miller is very replaceable, but we've seen quite a few guys come up and try to make that 4th line, and they just haven't been as good as him. Let's see what happens now that he has two guys who could be considered better than him on the same line in Glendening and Helm. A type of 4th line I've been waiting to see since we last saw Miller-Helm-Abdelkader(though I believe they were a 3rd line at the time).
Miller has some solid wheels aswell. I mean, more than enough anyway to be effective. What stands out compared to Ferraro is his reach and ability to break up plays with his stick.
I've been waiting for a fourth line I like for awhile now, too. I still have hopes the McKee puts it together in Western and becomes a good fourth liner to put next to Glendening. If someone like Bertuzzi can up their defensive game, having him in the other wing spot would give us a nice, ugly line to throw out there to grind other teams down with.
I wasn't trying to say Miller was slow, just not as fast as Helm and Ferraro. If we're looking to have a faster team, those two would have to be a part of it, imo. At least until Athanasiou was up. Also, it's the regular season, a time to try something like Ferraro getting more ice time and trying to stretch his game out. Miller's here and he's not going anywhere. I don't think sitting will hurt his game any. If Ferraro can't hack it as the season goes on, Miller can step in at any point.
