Ojo could be a very good player. He has the technical ability, he can be quick, and he is rarely injured.
If Bulut could do the same job with him that Warnock did with Ken Zohore (even for just a 6 month purple patch) that would be a major result.
But the things missing with Ojo are not technical or physical. He just lacks drive and makes poor decisions. Maybe a coach like Bellamy could do something about that - even over a summer pre-season - but I doubt Bulut will have the time or the inclination, even if Ojo was willing and able to change.
One year left on his contract?
