Like many have said here before, even if we had been lucky enough to have Panarin sign here, he'd have been given token chance at the top 6 and then moved to the 4th line to "earn it" playing 6 minutes a night and getting benched for the 3rd. Not good enough defensively etc.
Besides, #1 LW is spoken for. For some mysterious reason, it's the one position we have that's immune to experimentation.
