I watched the whole game last night and definitely think Kyrie was the reason we lost plus Lakers had an abnormally amazing shooting night: 53% from 3.
While I am somewhat disappointed in Hayward thus far, it's really not his fault AND he has had a great attitude about it. 
I really think it's almost time to put Hayward back in the starting lineup and Morris back to the bench. Hayward is not scoring yet but doing everything else pretty well: passing, the defense was good against Bron and taller McGee at times(as good as any guarding Bron), rebounds, etc. He is similar to Horford right now: does so many things well but doesn't always score a ton.
PLUS I feel like most of the game Hayward is not involved in the offense with kyrie, Tatum, Brown often doing their own thing. Kyrie has gotten a lot better-involving others but Tatum is the one that frustrates me. Yea, he had 5 assists last night but I feel he missed many open guys and instead forced up tough shots ala Kobe. Tatum is a really good player but just an average team player imo at the moment.
Morris should have been traded, as he is starting to return to the norm in relation to his shooting yet he still puts up shots.
Last night offensively and defensively he was abyssmal.
Kyrie had a bad night, we cannot expect him to play like an MVP every single night to win us games.
IF hayward is brought back into starting lineup, Brown needs to come as well, because we cannot have 2 inept offensive players in the starting lineup at a time.
I am all for Brown starting again. Even though Smart has played well, Brown would have never lost his spot if he were playing like he has since the first month of the season.
But, what are you talking about? Are you saying that Hayward is an inept offensive player or that Hayward is more inept than Morris? Because I don't see that at all. Hayward may not have all the same one on one moves that he used to have (that Morris lives for), but the rest of of his offensive game is easily just as good, and he blows Morris away with his playmaking.
Hayward is for the most part and offensive and defensive liability on the court.
Marcus smart is an offensive liability even though this is his best offensive season ever.
Offense needs another weapon if hayward replaces morris in thebstarting lineup because you cannot trust gordon at this point in time offensive....and I do not want smart picking up the slack.
Thats why if hayward comes in for morris, that brown has to come in for smart.  
Balance.
