I'm not sure with his reasons for that and maybe that's because he's just happy to play for a team that's building a new roster and reputation in the CS2 pro scene. Even though that's a tier 3 team, it's possible with his help and experience, he'll be a great help to his new teammates there.
He is probably on the brink of burning out, He had his loan spell on Team Falcons and Faze Clan but both didnt seems to work out for him. I mean technically he is not at his prime anymore but he is still a very good player though. BC.game obviously need alot of money to convince him but yeah eventually this could only be a short term deal or something until he gets back on his form
We will see how this is going to turn. Because based on my observation with that organization, they're not doing such long deals. So, you might be right on that and this is just some short term deal or if him and the team finds success altogether, then this is going to proceed for as long as they can and hopefully, they'll be on that term because we all just want to see them succeed and in CS2, it's also getting harder for these teams to get onto the top.
