For the betterment of their current campaign, I think Mikey can help them, but in terms of long-term relationships, it's not good to sign him back, they are just showing him that he can do whatever he wants. TNT or PBA should take things the right way. We all know what he did and how he disrespected the franchise. Now that he has decided to play back, is it just so easy for him?
That's how it is man, Mikey were able to play his card well, so he won. I would not even be surprise if TNT sign him with a good contract because it seems like the Mikey benefited on the current situation of TNT where they lose some star players, especially the import.
Once a contract is signed, we can pressume it's short term, it should be a long term like other standard contract in the PBA.
TNT can take this season as not for them, and re-group again next season or enter a trade that will give them players who can help them, though it's always the team owner's decision if MVP decides to re-hire him, it will be a safe comeback for Mikey for sure.
I don't know, but I have a feeling that they don't want to waste the talent of Mikey, and they believe he is very vital for the team's success, that's why they are gambling, talking to him and maybe sign him soon.
