Speedguns sure make fast bowlers look slower.
We may not have seen a speedgun reading at that time, but Srinath was a lot faster than your average Indian medium-fast strike pacer. He could extract extra bounce at times, and could bowl some unplayable deliveries that would have batsmen in really bad shape. I still remember what he did to Meryck Pringle- ghastly images of that injury were used on posters by fans in the stands.
Still, he wasn't too aggressive. He saw Pringle in such a condition, and it made him feel so uneasy, he had to have medical attention. Later on, he bowled a nasty one at Ponting, and then asked if he feels alright- being Ponting, he had some acidic, caustic abuses in response. Surely, he was the fastest Indian bowler ever, and fast enough to make a big impact, even if he wasn't a record-breaker for pace. If only India had a bowler as fast as Srinath and as aggressive as Zaheer- that would be ideal.
There's a joke- Srinath was unusually quick as a vegetarian. Then he started eating meat.
