Ravena is really overrated, he has the talent but he is not the type of player that could carry the team in the Finals. NLEX is still not a championship team even with Ravena playing, that's the reality, so maybe they'll improve a bit but they'll never be in the Finals.
You might see them getting into the finals once the players of top teams already retired, as you can see some of them are getting older already and of course they are not that good anymore. NLEX is also a good team, they almost got a good spot last governors cup and since this is also an MVP team, most probably they have a good budget to acquire more good players and by this, they can have that finals appearance so never say never. 
The very reason why it's a 5 man team, it's not just a single player who can dominate, even Fajardo on his primes needs the powerhouse teammates, he's been surrounded by great players, Santos, Cabagnot, Lassiter and Ross all are star calibers and not just relying to Fajardos shoulders. In terms of old and youngsters, it's still depends on how the management will balance the entire squad plus the influence of the coaching staff to develop the chemistries and brotherhood inside the team.
Maybe NLEX is still not that championship caliber, but the fact that it's a MVP group, we will never know what will be the future of this team.
. Every trade has its own drama but fans/community can do nothing about it even if we rant on social media, that will not still have an effect on the decision of Willie Marcial.
