I think it can be both: Lazar isn't conjuring this take out of thin air. I'm sure there are players (young wide receivers my guess) that really want Drake Maye in there. "Mutiny" is intentionally inflammatory language. If it was some other reporters, I'd say it was purely to drum up more engagement, but with Lazar I get the feeling he tries not to appear too "team-friendly" at times since he works for them, and went a bit too far.
Again though, doesn't mean the rumblings aren't there in some capacity.
