Bangalore Terming John Buchanan's theories on Twenty20 cricket as 'stupid and unimaginative', former Indian captain and coach Ajit Wadekar blamed Kolkata Knight Riders' humiliating eight-wicket defeat to Deccan Chargers squarely on the former Aussie coach.

"Buchanan has taken the Knight Riders' to the dept of the ocean with his 'stupid and unimaginative' theories. I find it shocking that he has been given so much of importance by the team management despite dividing the team. The body language of the players clearly indicated that everything was not fine with the team," Wadekar told Cricketnext.com on Monday.

"Changing the captain just a day before a big tournament is unheard of in cricket and by replacing Sourav Ganguly with Brendon McCullum, Buchanan has created a record of sort," a fuming Wadekar added.
