Replacing Klein with Cory Littleton

Littleton is 225 lbs. Klein has manned our SAM/MIKE spot ok. I think Davis is the only WILL backer that we need. We need to pair Davis with a bodyguard type. A bigger, stouter guy that can go take on that guard at the second level and allow Davis to use his athleticism. If i'm gonna replace Klein with an expensive backer it would be Jamie Collins.
