Mine is not expecting him to be Chris Pronger.
I watch what he does. I see him objectively and I like what I see for the money he costs.
Some fans might expect him to be Chris Pronger, there's no doubt about it. Those people aren't on this board. The people here are generally more intelligent than that.
That said... my issues with Brewer are largley expectation based. Brewer has played well in a Blues jersey at times. I expect a player that is making $4.5M per year to do that all the time, not for 6 weeks a season. And, IMO of course, the difference between his good play and his horrid play is almost exclusively bad decision making. The guy has skill and can even be very good at times in his own zone, he just hasn't been able to do it consistently.
Why is it you switch back and forth from thinking adult to adhominem attacker? Why can't you be consistent?
I think the biggest issue is what he's asked to do, based on who he's paired with. When he's not comfortable with his D partner, all hell breaks loose in his mind, then watch out.
When he's comfortable with his D partner, think Salvie and Polak, he's a very, VERY strong defender, good on the transition, largely by skating and not passing...which sucks...and is good at manning the point, just not shooting...and he'll put in his 30-40 points each year.
When he's uncomfortable with his D partner, he tries to do way too much, and screws everything up.
