Anyway, my point is only that the fact that Shakib plays for Bangladesh has worked in his favour as an all-rounder. I think most other countries (particularly South Africa, England and Australia) would probably have developed him more into a specialist batsman and kept his spin part time. He'd be a 50 average batsman who picked up 2 wpm @ 40 instead of a 40 average batsman and a 33 average bowler picking up 3.6 wpm. Alternatively he'd average 30 with both bat and ball and pick up 4 wpm.
But Shakib plays for Bangladesh who have no other bowlers who've taken 50 wickets or more that average less than Shakib's 33. So he gets an average of 23 overs per innings, which is a full time bowling workload (Lyon gets an average of 20 by comparison).
While you're not totally wrong, I don't buy that this is totally unique to Shakib.
- Sobers opened the bowling for WI, and as good as he was, it was primarily because WI's fast bowling resources weren't amazing. In most teams, he'd have been at best a 3rd seamer playing a supporting role and wouldn't get anywhere close to the 230 odd wickets he did shouldering a massive bowling workload for WI.
- Imran Khan towards the end of his career could afford to basically become a part time bowler and bat as high as 5 because Pakistan needed his batting, which wasn't particularly deep and could afford him bowling far less since Wasim and Waqar had emerged. And yes, I did just use Sobers and Imran to make a point about Shakib
Shakib may be a slightly more extreme case but his performances just can't be written off. It also comes with it's own challenges which others don't face:
1) The only other consistent batsman in his lineup over his entire career is Tamim and he's constantly scoring runs amidst collapses and coming in at 10/3. He could easily hide down at 7 and pump up his averages with not-outs which would ironically make his statistics even more appealing to the eye. But he has to bat higher up and it should be to his enormous credit that he's still averaging 40 odd.
2) And bowling as part of a rubbish lineup as the lead spinner is a tough job. Especially for a finger spinner. More than any other form of bowling, finger spinners rely on pressure being built constantly to force an error from a batsman. He's had ****all support from the other end to keep things tight and help him take wickets. I could easily see him taking fewer wickets overall but having a way better average and SR if he played for Aus or SA. If he had Steyn,Philander or Hazelwood at the other end, imagine how much easier his job becomes... no one else is giving anything away, and he can do his thing just chipping away and getting 2-3 cheap wickets every game.
