I am sorry but as good as Trescothic is there is a little west country bias going on. Tresco is a wonderful player, but not in the same league as Hobbs who opened the batting on uncovered pitches all over the world.
Ask yourself how many first class hundreds a player has scored - and then compare that to Jack Hobbs.
http://www.cricinfo.com/england/content/player/14225.htmltest match average of 56 in the days when 35 was a good average (not like now when 45 is a good average)
197 first class hundred, with none in his peak during the first world war.
The first cricketer to get a Knighthood for services to sport.
the finest opening batsman of all time.
I will nod to Sehwag as the most exilerating opening batsman of the modern era, but that doesn't make him the best... Tresco isn't in the top ten.
