Not much, his missed tackle count is exaggerated*, his position in the team is taken for granted as no one looks like taking it off him warts and all, and he has played wing for Leicester before, just not recently.
Cole hasn't had a great scrummaging tournament its true but scrums go wrong as units; maybe Youngs doesn't help at scrum-time, green looseheads certainly don't help, and neither does a relatively lightweight second row. Will be interesting to see how he goes on the Lions
*Tuilagi made 16, missed 2. BOD 33, 4; D'Arcy 10, 1; Marshall 10, 0; Fritz, 12, 1; Canale 30, 4; Garcia 13, 4; Benvenuti 10, 3; Scott 42, 9; Lamont 40, 7; Davies 19, 2; Roberts 24, 5; Twelvetrees 12, 2; Barritt, 32, 4
That's every centre who played a major part in the tournament (bar the French ones who the DT stuffed up on) - Tuilagi's miss rate is roughly equivalent with O'Driscoll and Barritt and a great deal better than most people there. Missed tackles and Tuilagi is becoming something of an accepted myth quite quickly for no good reason.
One might also say the same about Roberts and defensive excellent the next time it comes up too now it's there...
