It's not an uncommon move. A lot of players of Caribbean heritage based in England often play only a handful of games for their national side. I guess the thought of not losing their place for their club side is more important than qualifiers for the Gold Cup or facing a battering at the hands of the USA or Mexico.
For example, Jason Roberts won only 12 caps in 10 years for Grenada, Ruel Fox won two caps for Montserrat two years after he retired and Robbie Earle won only eight caps for Jamaica despite a top flight career of almost a decade in the '90s. I think for most the call up seems fun at the time, but the novelty of travelling across the Atlantic to play qualifiers at small grounds alongside the less professional local call ups soon wears off.
I admire Shandon's ambition, but I feel there's more to it than hoping for the England call on this occasion.
