Walker is literally a 21 year old version of 32 year old Jordan Phillips. Maybe they just want Phillips to give him a jump start to playing as a big man that's not a 1 tech in the NFL. I'm certainly not going to crap on Phillips because he loves playing here. It's not his job to decide who's fit to be on the 53 man roster. He probably has as much to offer as anyone else after Oliver, Sanders, Jones, and Walker. Maybe they are going to trade Jones? Who knows.
