The reason why I wouldn't change the lineup is because I dont see anyone that they could actually get that would also be an upgrade. I dont think the switch that you suggested is an upgrade at all, I think it's closer to a downgrade.
Thats exactly what I'm thinking as well. This exact lineup did have pretty good results not that long ago but now, suddenly, they struggle against a lot of teams. Maybe their old coach Kassad meant waaaay more to the team than what we might think.
I think dexter deserves a chance... he has a skill that the others lack in that he's more unpredictable. He would be able to catch people off guard or make them watch their backs at least. I think this is what 100T lacks. As for the other change, it's a tough one, Gratisfaction is rather inconsistent but he has his moments.
