A couple things that jump out at me from that article.
First off, I read it, considered it and realized it was Feschuk after... thanks, I broke my rule...
Anywho, the article is from Nov 18 and there were far more viable criticisms at the time ( last nights game notwithstanding ) when Jonas was having a tough time for a variety of reasons, after that article was published Jonas won his next 4 and had a pretty good record on the whole after that, prompting sound applause from Burke and staff.
I think the truth is somewhere in there though, that a 'drop and block' style isn't completely right for Jonas, though I contend that's not the entirety of Allaire's system, certainly the athleticism and reactionary capability of a goalie is intertwined with the better ones.
If I just juxtapose a few of the comments from that article...
Elkin..."But for some reason those goalies (J.S. Guigere et al) were able to take part of the blocking strategy and combine it with some athleticism and some reacting as well. For some reason, Gustavsson hasn?t been able to find that fine line.?
Mclennan...?I don?t think (Gustavsson) has been able to adopt Allaire?s style completely.?
Weekes..." But honestly, based on his frame, I think he needs to spend some more time in the gym. . . . The toll the game takes on you physically ? I don?t think his body is complete yet.?
Gustavsson..."Over here, it?s more about getting the timing and learning where and when to be.?
...I think we see a goalie who's not really had the development time due to illness and needs the work to get his game to a point where he feels comfortable enough to just forget about it during play, he's still thinking it in a lot of ways.
One thing I don't see in that article is a solid refutation of Allaire on the whole either and the comments about Jonas weren't all that surprising to me, generally.
From Nov 19 to Jan 31 Jonas went 12-6-1 with a pretty heavy workload in November and January, Reimers return in December was pretty unspectacular in terms of success but the Leafs seemed determined to play him ( Reimer had 11 starts, 3-4-3 and 1 incomplete where he gave up 3 and got yanked to Jonas' 3 gp, 1-2, and one of the gwg against was a 5 on 3 ppg after coming into relieve Reimer against Florida...). Not entirely sure what to make of that but, there it is, I think he just needs time as he's shown signs that he can put it all together and play an effective hybrid style between his innate abilities and the positional play his coach is teaching him.
