Oakland Raiders running back Rashad Jennings was speaking to a group of local high school students earlier this week when the conversation turned to the importance of being prepared when opportunities in life arise.

The veteran backup is certainly qualified to speak on the topic, having received a crash course on it over the past 15 months.

Jennings will make his second start of the season Sunday against the New York Giants while Darren McFadden rests his sore hamstring. He also started six games for Jacksonville in 2012 while Maurice Jones-Drew was sidelined with a foot injury.

The message Jennings delivered? Don't wait or it's too late.

When McFadden got hurt last week against Philadelphia, Jennings responded with his first 100-yard game in nearly three years.
