More about individuals not showing up consistently enough.
Also as much as I don't like the way of chopper's calling, Spirit's T sides have looked fairly decent lately. The issue resides in CT sides. They play super passive, not taking any risks and hoping for a miracle.
In general they don't have many setups on CT side. For example I've never seen them do this boost in under on mirage where you can see the enemy crossing towards the mid box. It's quite easy to do, and you can catch your enemy off guard once or twice.
Back in Antwerp they played one of the best CT sides I've ever seen in my life. On every map. Their teamwork was just on another level. Since then it's been getting worse and worse.
Also, they used to be one of the best teams in the world when it comes to pistol rounds and so far this year they've had like a 20% WR in pistol rounds. Like they were losing every pistol round in Katowice. At EPL they lost 3 pistols against Astralis, 5 vs FORZE, 2 vs Liquid and against NAVI they lost all pistol rounds. One pistol round on Anubis and the game would've been different.
