I was never sold on Taijul. Shakib looks a far better and intelligent bowler than him. Sunzamul has a long way to go. Success against Zim cannot be the benchmark for any of these left arm spinners
.
But Mehidy is definitely better than those needing pitch assistance. He wasn't used at the right times by the skipper in this test in my view. Plus the pitch was an absolute road all the way till day 5. Mehidy is still young and learning though, with lots of talent.
What they are lacking is a quality leg spinner. That would have made things interesting even in this match.
Recently read that Sunil Joshi is the spin bowling consultant for BD. Is that a full time role? When did he join? He has had some eye-catching success with domestic teams in India. Rest of India realized that there was a serious cricket team from Jammu and Kashmir when Joshi coached them into knock out stages of the Ranji trophy a few years back, in his first attempt itself. They even beat the mighty Mumbai team along the way! Then he moved on to Assam and got them to get some really good results. Then he helped Hyderabad get back to their respectable days after the slump they sufferered for over a decade - after producing VVS Laxman. But stragnely, he did not stick with any team for more than a couple of seasons though. He would be invaluable for the young left arm spin brigade of BD.
In fact, Zim should have explored an opportunity to work with him if he was available. Both from training the Chisoros, the Wasakadzas, etc. to training the batsmen to face left arm spin. If I'm not wrong, he holds the record for most wickets for a spinner in the history of Ranji Trophy cricket. Just happened to have his career coincide with the golden era of Kumble and Bhajji, meaning he did not get much of a chance at the national level.
