True, he's played more than Lara in the last ten years ( in ODIs atleast). But his superiority isnt just becaue of more matches.
As the records show, the gap between them is 5200 runs in 89 dismissals- thats a stupendous average of almost 59 - which is a huge margin of difference. Not to mention, Tendy also has 22 tons and 20 fifties more...scoring 42 times over 50 and 22 times over 100 in a 90 match span is a fairly huge gap in performance.
Not to mention, at a significantly higher strike rate ( lara's career strike rate is in the high 70s and Tendulkar's in the high 80s. However, you'd find that Lara's strike rate in the early 90s was higher,when he batted with the likes of Haynes, Richardson, Hooper etc. and had very little pressure on his shoulders. Tendulkar's strike rate has been well over 90 since he's taken to opening in ODIs...so in the last ten years, the strike rate difference is close to 20 runs/100 balls.
If the difference between player A and player B in ODIs for ten years is a near 60 runs average, 5000+ runs, scores over 50 in almost 50% of the innings and a 20 runs/100 balls strike rate, thats a pretty categoric superiority.
