I looked on hockey-reference and compared Jake to J. Quick. I compared their same age seasons and Jonathan Quick didn't hit his stride in the league as a top end goalie until their cup year of 2011/2012. As far as seasons in the league, that's this year for Jake. Up until that point, their numbers are very similar. I'm not saying Jake is J. Quick. I'm saying most goalies don't fully develop until around 28 it seems. Bishop, Quick, Crawford, are 3 that come to mind who were in the league 5-6 years before becoming a true #1 and reaching their potential. Again, I'm not trying to defend Allen. He's played awful his last 3 starts. Before that, he was playing well, but not getting goal support. I'm arguing that we don't know if something will finally click next year, and he won't have this mid-season funk.
JR's article pointed out that he always seems to have a dip in the middle months of the season. It looks like a definite trend, but like I said, maybe he figures something out by next year and reaches his full potential for the whole season.
I'm for giving Binnington and/or Husso a shot next year if they're ready. One of them might be the long term answer. If Jake can't figure that part out and Armstrong really needs to move him, I guarantee, there will be a taker.
