Nope !!!! Its just their mental state. They start doubting themselves. Playing too passive wont take 50/50 peeks and they lose cause of it.
As we saw there NUKE is really top class ( they beat coL and Vitality on it) , D2 they were one of the best teams at start of the year, TRAIN ( only big lose was vs ASTRALIS ( that too in 2nd overtime, else they beat alot of good teams on it), INFERNO they beat astralis and their T side is good but CT is kinda meh alot of mistakes) , OVERPASS unlucky vs VItality but they improved ( as flamie said) . Mirage not the best map for them . Vertigo perma ban. But yeah most of the part is their mental state. If they play with 100% confidence, they are really good team. The only player which can be upgraded is flamie but I think he has alot of experience and idk maybe just he plays with too much pressure.
