Reeder, Kaiser, Hager - none of these guys have Littleton's athleticism. Kaiser and Hager can't stay on the field. Sorry, I know injuries happen but somethings wrong when you can't even make it through any games when you get your 'big chance' and you've done nothing up to that point.
And none of the 3 can cover like Cory.
Howard has potential but would need more time to develop. Hopefully there will be some options in draft or free agency if Littleton does walk.
