Exactly my point. You don't need technology to figure out that you need to bowl short at Hughes, or full at KP do you? (unless you are either Shravi or ballers)
They are two isolated examples, much like the one of Murali Vijay. Technology doesn't work in any and every given situation, however
in theory, it does help. Maybe you need to learn the difference between theory and practice.
I thought my last comment was my last comment, obviously not.
During the last six years Hawk-Eye has developed strong relationships with the coaching staff of all the major cricket nations, with the likes of England, Australia, South Africa, and India all using Hawk-Eye data.
The pure tracking system is combined with a data repository and archiving capabilities so that it is possible to extract and analyze trends and statistics about individual players, games or ball to ball comparisons etc.
"All the statistical data and analysis of the players and game will be supported by graphics and visuals for better understanding and improving the performance."

The end of the article is particularly insightful and informative as it shows specific examples of the different softwares/services used by teams/boards/players/academies.
I'll try to say this one last time. Technology does have an influence on the game. It can:
a) Remove technical deficiencies in a batsman's technique or make them less evident
b) Allow a batsman or batsmen to prepare better against a certain bowler, bowlers or tactics.
c) Allow a bowler or a team to make a plan for a certain batsman.
However, this physical preparation is just one aspect of it. It does not take into consideration the mental preparation involved. It takes not only ability and physical preparation to pull of these plans, but mental fortitude. In addition, how well a player or players pull off these plans is determined by their ability and/or form. The extent to which these plans succeed or if they succeed at all is dependent on the batsman's form and/or ability. However, it is also influenced by weather conditions, pitch type, ground size, etc. The degree to which a side plans, how successful these plans are and all the aforementioned factors may be evened out by the emergence of flatter pitches, more rules in favor of batsmen, shorter boundaries and an overall decrease in the quality of bowlers.
Therefore, it is difficult to determine whether in fact this has made it more difficult for Sachin, or easier, as there are so many other factors involved. I'll say it again. Technology does have an impact; it just difficult to determine how large this impact is or will be and in whose favor it is in.
