Yes I’m sure the consummate professional magically became lazy and stopped playing hard when the qb all of a sudden forgot how to throw a football.
Are you claiming that Moore hasn't been running poor routes and just playing flat in many games this year? Because if you are, then you're wrong. The tape proves it, and there's a reason why so many people are being critical of his effort. It didn't get pulled out of thin air. No one is saying this about other guys on the team, so why Moore?
But if you're claiming that the reason why Moore isn't playing as hard is because Caleb has been bad, then you're no different than those you are criticizing. If people are saying Moore has been bad in an effort to make excuses for/defend Caleb (as you claim), then you're essentially doing the same thing by saying making excuses for/defending Moore's effort by blaming it on Caleb's performance.
Regardless of how Caleb is performing, Moore needs to do better. It's as simple as that. And when we have multiple Bear players saying that the team needs to put in more effort, and that coaches were letting things slide in OTAs, practice, etc.... and then you watch the Bears play and see who is and isn't putting in max effort, it's easy to see where the problems lie
