Semi-Pro
You're entitled to your opinion, but then we should at least make arguments for our point of views.He has a very high ceiling??
Kyrgios has a high ceiling but no discipline or consistency.
Rune is the same level as Ruud/De Minaur- very good average players with no outstanding skills or attributes.
I think Rune has a high ceiling because he has a good all court game and in terms of coming to the net he's the most aggressive player on the tour. This style of play is tricky because you need to master a lot more different shorts and variation which comes with a higher risk but when it succedes it also has the highest ceiling.
I don't say in any way that a high ceiling is any guarantee for success. Persistency and stability are more important.
I haven't been able to watch a lot of Rune's matches lately, but I will give you an example from UTS in Oslo when he played Ruud. Rune won the first set 21-6 and he played absolutely brillant tennis. He then dropped significantly in level and lost the next 3 sets.
His first set was at an extremely high level (ceiling) but he lost the match due to lack of stability and persistence.
I have great doubt about Rune's mental ability and the choices he makes outside court. I don't have any doubt his ceiling is extremely high. That is why so many refer to his game as hot/cold.
If you can elaboration your point it would be nice.
