I think that Sarver and McD are a lot more level-headed than we (the fans) are. I am 100% sure that firing the coach has not even crossed their mind. Anti-Igor stuff is limited to a small number of posters on message boards. As for trades, I am sure they are looking at different options, but it really sounds like they are not in a hurry, and it also appears that they don't share our intrigue with various stop-gap measures.
I also agree with you on how strange it is to watch the Suns as a defensive team. For the past few weeks, when thinking about team identity, which is the first thing a young team has to create, my mind really goes to defense. It looks like the Suns are building an identity as a defensive team. Also, if Ayton plays like he did last night, building that identity is going to get a hell of a lot easier. Sure, Booker is a poor defender, but you can get away with one person not being a good defender if the rest of the team is made up of defensive stoppers.
Looking at the roster, outside of Booker, Warren, and Ayton, there is no bad defender in the rotation. Maybe Daniels and Crawford, but those guys are in the extended rotation short-term. Both young PGs are good defenders, all of the young wings are outstanding defenders, backup Center is an outstanding defender. Warren, while not great, is not a terrible defender, and Ayton shows signs of being able to be a good defensive player. Last night, his rotations were on point, and very aggressive, he got three blocks and he affected quite a few shots in the paint. It's amazing what happens when someone with that size and wingspan challenges every shot. Hell, even Booker played defense the last few games he played. I don't think he will ever be a good defender, or even an average one, but the last few games he played, he didn't look awful or non-existent on defense.
