No way he can tank the summer. My opinion is assuming he doesn't. Brown is a superior skater to both Conacher and Killorn, which is yet another advantage.
If you look at my first post again, I have Brown inked as part of the 11 forwards, leaving two open slots for Norfolk guys. IMO Conacher and Killorn is fighting with Wilson Labrie and Connolly for those two spots. Not with Brown.
But Brown can't take anything for granted. And for all I know, the org might have Connolly inked too, and there is only one slot open.
