Better watch out. Having an opinion rubs some people the wrong way...

just kidding and I think some of the longer tenured posters here get the joke.

Welcome to the board.
I don't know that anyone knows what to think with the goalies right now. I often post about my own frustration when it comes to reading Jackson's mind as it concerns his netminders. Just when I'm sure one will start, he starts the other.
While it is only my opinion I actually think Johnson is the one that brings the higher upside to the ice. He's just incredibly inconsistent. I think he is completely capable of the kind of play we saw from him in New Hampshire last year in the NCAAs on most nights. His play then against two high powered offenses (I think Merrimack and UNH were the top two scoring teams in Hockey East last year) was huge. He was in large part the reason we saw the Irish advance against UNH, as they peppered him with nearly 40 shots and were in his face the entire third period. I think you might be placing a little too much blame on him for the NCAA semi-final loss, as Notre Dame took an uncharacteristic number of penalties and the penalty kill in general took the night off. Yes, he didn't play well in St. Paul either, and as we've seen he can certainly have a meltdown of a start like the ones against Lake State or Northeastern.
Steven Summerhays brought a great resume to Notre Dame and a reputation as a very competitive guy. But in his (admittedly) limited game opportunity or his practice preparation he has yet to show Jackson that he needs to be handed the reins as the number one guy. His numbers last year in 12 games didn't blow away anyone, and so far this year I think his record is better than his performance. I do feel like he played a very good game Saturday, and gave the kind of performance in net this team really needed. It seems that quite like the backup quarterback is the most popular player on a struggling football team, the backup goalie is in a similar position on a team with netminding issues. Summerhays will eventually get his chance if Johnson struggles for an extended period of time.
I think the current struggles are a combination of a lot of things. Inconsistent netminding, a schedule with too many games compressed into too few days, final exams, and a persistent bug that made its way around both the campus and apparently quite a few college hockey teams recently. I think coming out of the break we will see if Johnson can reassert himself as the obvious starter, as well as if a few other guys can fight their way out of a few slumps.
