There needs to be more money in challengers and more points in ATP Q matches, and ATP R1 slams. And maybe select 10-12 big challengers per season that reward 120 points, and the rest keep at 60. Because the same problems that were happening when I made this thread are still happening. Some of those Asian challengers reward 125 points yet have cutoffs in the 300s.
Thing with the above while it's all true. The ATP have shown they don't care too much when it comes to this level and won't do anything about it.
The 70-120 spots, there is very little difference between these guys, but they have to live and play a mix between Challengers and ATP events. Klizan, Dog Balls did it to get their ranking up but were able to stay there. The guys like Junqueira, Prodon just aren't good enough.
Bedene will be a good test next season, then you have Kavcic who wins matches on the main tour though normally loses at QF level there, which is about his realistic level when he does well at the moment.
