this year the award was presented posthumously to xavien dobson, who died in 2015 after shielding others>> zaevion gave his life saving others. what's our excuse for not acting? we have to ask ourselves, is this the world we want our kids to grow up in? are we just going to accept these tragedies as the price for our freedom and move on? it's up to all of us to build a country that's worthy of zaevion's promise. that's what we owe him. that's what we owe all of our kids. >> very powerful message there. also last night, vice president joe biden was on hand to present the jimmy v. award for perseverance to legendary sportscaster craig sager, who's battling cancer. >> time is something that cannot be bought. it cannot be wagered with god. and it is not an endless supply. if i've learned anything through all of this, it's that each and every day is a canvas. so i will never give up. and i will never give in. i will continue to keep fight i ing, sucking the marrow out of life as life sucks the marrow out of me. i will live my life full of love and full of fun. it's the only way i know how. th
