Yes, it was incredibly stupid and I say that as one of his biggest fans. I've been thinking for months OK so far so good, I really hope he doesn't mess up in the playoffs and then he can't even make it through one full game without losing it, just so disappointing. But yeah, on the whole he's a net positive no question so what can you do, you take the good with the bad and live with it.
I still can't help but feel Babcock is partly to blame, if I as a huge Kadri fan was worried about him you would think Babcock would be too and if so, he'd sit him down before the playoffs and make sure he understands what he needs to do. Some have said that Kadri should know anyway but no, the guy's a hothead, this is well known and why not just take 10 minutes to talk to him? Nothing to lose and everything to gain, cover all the bases etc. I can't help but feel like Babcock should have done this but he didn't and it cost us. Not to excuse Kadri, this is on him but I just feel like it's partly on Babcock too.
In any case, this can't ever happen in the playoffs again. Regular season I don't even care that much if he loses it every now and then, some people get on his case about it but honestly, it's not that big a deal to me. Playoffs though, that's another story. This simply can not happen ever again, period.
