You don’t think reasonable protects him from disciplinary action?
It kind of depends on how the Flyers want to proceed right? Chuck Fletcher has done everything wrong from the jump since he took the job, so it wouldn't surprise me for them to take the "just hope this goes away" tact and let it fizzle out.
If the Flyers were to pursue this, they'd first have to hold Tortorella responsible as he let Provorov play after he chose to sit out for warmups. If it got to the point of any kind of grievance filed against Provorov, you're probably right that "reasonable" is broad enough that they can make the argument that Provorov's belief system makes him incompatible with supporting Pride night. To that end, there is precedent across Europe with predominantly Muslim footballers not taking part in displays of Pride / the Rainbow Laces campaign - all this to say my initial take is probably wrong and, beyond the unlikelihood of the Flyers pursuing any discipline, there are enough examples of precedent elsewhere to keep the NHLPA from having to argue directly that Pride-themed warmup sweaters are unreasonable (merely that they can be interpreted as such by players based on their beliefs).
Obviously, it's a massive cop-out, but this chud has already taken enough attention away from the goal of Pride nights so it's not worth belaboring the point
edit: on a more positive note, the redirect on Provorov's
MoneyPuck page is great
