Quote: Rogues Gallery "No he hadn't.'"
According to the stats on the respective Wigan and Saints sites:
Tomkins appearances: 2010 = 30, Career = 61, so 31 first team appearances before the Four Nations at the end of 2009.
Eastmond appearances: 2010 = 23, Career = 41, so 18 first team appearances before the Four Nations at the end of 2009.
Not sure if they are accurate, but they're from the official sites. If you also factor in a lot of Kyles's pre-2010 appearances weren't at 7 due to Long being at the club (whilst Tomkins played 6) then I'd say Tomkins had far more top level half-back experience than Kyle by the time of the 2009 Four Nations.
