NFL quarterback finds unlikely inspiration in British politician

Colin Kaepernick is the Milwaukee-born 6ft4ins, 230lb quarterback of the San Francisco 49ers - one of the most powerful franchises in American Football's NFL.

Iain Duncan Smith is a Tory politician who went to school in Solihull, was much derided when leading the party, and now leads the Department of Work and Pensions.

Yet somehow, the gridiron superstar has drawn inspiration from IDS - posting a quote that Duncan Smith used at the 2002 Conservative Party conference in a bid to re-frame his image (he was deposed as leader the year after).

Do not underestimate the determination of a quiet man.

The quote sits on Kaepernick's Twitter profile and is attributed to a certain Iain Smith - the absence of "Duncan" is perhaps the reason it has not been more widely acknowledged.
