I suspect Noreau simply can't skate well enough for the AHL. This is based on what he's done in preseason, as well as his lack of points in the ECHL. We all know that he's a defensive player, but someone who can see the ice well, knows how to skate and how to make a good first pass out of the zone will run up some points.
Nothing big, but on occasion you'll get a secondary assist because you sent the puck out of your zone to a guy who moved into the offensive zone and passed it to the scorer. Or while on offense, yes you are on the blue line, but if you can see the ice well, you can occasionally send the puck to someone who scores.
That said, Sammy The Bull is presently ahead of where Dale Purinton was at the same age. The Bull is taller, a better fighter, scored more in juniors, didn't need to get sent back for an overager season. Purinton needed another half a season in the ECHL after his overager year, so if The Bull can get called up to the AHL at some point before the end of the 2014 calendar year, he'll be ahead of Purinton.
Purinton wound up spending 4 years in the NHL as a #7 defenseman. If The Bull can do the same, he'll make about $4 (or $2 after taxes), which is good enough to give him a nice start financially if he saves the money instead of wasting it.
Potentially he could be slightly better than Purinton and establish himself a role as a bruising #6 defenseman. This would be great for the Rangers, and would set him up financially for life with probably about $5 after taxes for his years of NHL service.
I think that's the limit of what The Bull should be looking at. Expecting more than a #6 defenseman out of him is not realistic, he'd have to significantly exceed expectations for that to happen.
