They might well kill you
but the Gough comparison somehow sounds right. That's not to say he's up to Gough's class yet. Maybe the comparison will sound natural in a few years time.. maybe not.
One thing one could always say with certainity about Zaheer is that he's genuine talent AND shows a capability to improve and learn after each tour. Srinath, an excellent paceman never became truly great solely because he never really seemed to learn... he was usually unplayable as long as he pitched the ball up. But he preferred to bowl it short half the time, and has basically underperformed too often for someone that classy. No international batsman could really say he could handle Srinath well. Even Sachin had trouble facing Srinath in that memorial match in England.. IMO, he lost an opportunity to become an all-time great.
My criticism of Zaheer and infact all Indian pacemen of the last few years bar Srinath was that they never seem to take the five-fors, and never manage to dominate even inthe odd match (Prasad and Srinath were the only ones to do this in the last several yearsafter Kapil-Prabhakar).
The pacemen Indian fans call 'good' are usually guys that are penetrative enough to take the first couple and last couple of wickets in a match, between them; the odd good spell in between would be a bonus. Thank God for Srinath!!!
Zaheer is special because is able to compare well with other good international bowlers in that he can consistantly trouble batsmen throughout a test match. He is one Indian bowler who gives the impression that we could have a bowler that opposition consider a very serious threat. Right now, they probably take a note of him as a good bowler, but certainly no more than that. And I'm waiting for the five-fors..
Since he's not there yet, it's probably not smart to say he compares to, say, Pollock or McGrath who are both wicket takers as well as high quality, consistant, bowlers.
