McIlrath looked like absolute garbage earlier in the season. Don't want him anywhere near this team right now. Hunwick is much more serviceable during this time, and will be the one called on to play in Klein's (potential) absence.
That was literally more than 4 months ago and he saw limited ice time. I watched Hartford this weekend and save for one shift against Manchester, he was pretty ****ing awesome. Much better than where he was even just a month ago.
If this is going to be a short term thing then it doesn't really make sense to call him up but if Klein will be out 2+ weeks, I want to see McI get a few games in. Doesn't have to be every game, but an extended look to see how he matches up against NHL competition in the heat of a playoff race can give the organization a pretty good idea of where he stands in terms of NHL readiness.
I'd be lying if I didn't wish he was in the game yesterday. The "deterrent" didn't deter Wilson from running around like an idiot, McIlrath at the least would have kicked the crap out of him.
