Are you going to use only the best players even if they are quite old?
In my mind, the NT is the best team with the best players and, as a manager, I will want to have the best possible results, whether with young or old players. But in BB, we have the 33+ limit, and it's more difficult for me to select this player type.
On the other hand, and for example, it would be hardly conceivable to do without Hinata Oyanagi next season, despite his 34 years.
