The Arizona Cardinals, in a bid to be quicker (especially with an ageing Larry Fitzgerald) signed up an Olympic gold medalist.
They actually did it a while ago, back on March 6. But details of this speed training are just beginning to come to light.
Twice Olympic Gold medalist Roger Kingdom is the man charged with delivering his prowess to the team.
The idea, as explained in an interview with ESPN, is doing further work improving a players strength and conditioning but also their running "mechanics".
As well as further weights and specifically designed exercises, a lot of work is being put in to adapting the players posture and giving them the right strength and positioning to better the athleticism they've already been gifted. In essence, this is a much more tailored version of high intensity interval training.
Kingdom's medal wins with the hurdles is a testament to his knowledge and discipline in this field, and he was also a former football player himself for a time.
The Cardinals haven't been in the playoffs since 2009 and their ageing star, Larry Fitzgerald has put back his own retirement for another go at getting them back to the big game.
