Why Brian Lara and Vivian Richards are such unique cricketers in my opinion?

They have dictated the Game in their own term and they have simply Dominated the Oppositions with higher SR in a Consistent basis with Volume of Runs and Longetivity.

And Fortunely Lara and Richards are two of the Most Complete Batsman too who has equally Dominated the Great Fast Bowlers and Spinners of their respective Era and that too with Aesthetics , Style and in an Entertaining fashion.

Richards was more Brutal and Fearless while Lara was Intense and Rebellious. And Both Viv Richards and Brian Lara are equally Successful in ODI Formats too and hopefully in T20 too due to their style of play if they would have tested.

Viv Richards simply Dominated the Oppositions mercilessly while maintaing Great All 4 innings and Away Records while Lara despite of playing in a Declining West Indies Team from 1995 to 2007 but Still he managed to Score 10,000+ Runs with 34 (100s) , 9 (200s) , (300s) , (400s) and (500s) as well as played More Iconic innings than any Batsman from post WW2 Era. And Richards and Lara's Sole Influence are the Key Element for their Team's Outcome and Results as in Batting Department their Team Heavily Relied on them throughout their Career

So, The Point of the Post is, Lara and Richards played with 60+ SR throughout their Career while playing 125+ Test and they have Great Head to Head (H2H) average against the Top Bowlers of their Respective Era and all these Dominations with Longetivity requires Great Courage , Leadership and Single Most Contributions for their Team's Total and Success.

And at last, Even if Viv Richards and Brian Lara are not as Textbook Complete and Technically Perfect as Sachin Tendulkar and Jack Hobbs but maybe not even Tendulkar , Hobbs , Sobers  , Headley , Hammond or Pollock have Dominated the Oppositions and Great Bowlers of their Respective Era as Richards and Lara did with High SR and that too with Great Consistency and Longetivity after playing 125+ Test , Scoring 10,000+ Runs , Making 30+ Centuries in their 15+ Years Career.
