The Indian team is over dependent on Bumrah

I feel since the start of this year the entire team performance is heavily dependent on Bumrah performance which is bad thing. Bumrah has taken more than 50 test wickets this year followed by Siraj with almost 30 test wickets and after them none of the bowlers have more than 10 test wickets. In this Ind vs Aus series we can see none of bowlers are performing at their best ig and Rohit keeps on calling Bumrah to bail the team out of defeat again and again. Our batting line-up looks terrible at the moment , Rohit - Kohli are declining, youngsters other than jaiswal are unable to take in the pressure and bail the team out of the jaws of defeat unlike Kohli and Rohit did during their early stages. The only reason we won the T20 world cup was because bumrah was used like a machine by Rohit to take important wickets and slow down the innings thereby putting pressure on the batters. Rohit is using Bumrah like a machine to win matches which is not sustainable in the long run. If for incase touchwood( I HOPE NOT)he gets injured, the entire team will fail as we have been wayy too dependent on him. I just hope he gets a break sooner than later because he frankly deserves it and other players in the team start performing consistently and take some pressure off him. Its not good for the team in the long term to be dependent on a single player. What are your opinions on the matter?
