Partly that, but partly Iowa is close enough that he can shoot down there is he needs to get more games. I will be interested to see how Hlavaj, the new goalie that they signed, does in Iowa. I think he has some talent, also.Have to wonder if this extension is a bit of a pat on the back for a real solid camp, before sending him down. Like, "here's a cookie as a show of faith for the track you're on - before we send you down until you're needed". A sort of reassurance that the organization is committed to him as the future, but probably realizes that carrying 3 goalies is a dumbfoundingly stupid idea (especially when one of them is young like Wallstedt and needs to be playing a lot).
Part of this signing is also about Gustavsson. After a fantastic 22-23, he took a big step backwards last year, and has looked uneven during the preseason. I think Guerin wants to put the pressure on him to perform well, and if he doesn't will look to move him. There have been some mutterings about him being not being in good shape, and committing himself to training after signing his new contract last year.
The original idea was to have Wallstedt and Gus(who is still young, for a tender)man the nets for the next few years, but if Gus has another mediocre or worse year then he will be gone at the end, or even sooner, if Wall plays well and shows that he is ready for the starters spot in 25-26.
