Eric Luttrell flagged rookie Ray Davis as the best late-round handcuff on the board. With chatter that James Cook could stage a mini-holdout over his rookie-scale contract and the Bills opting not to draft another back, Eric sees Buffalo boxed into extending Cook or elevating someone from within. At 215 pounds Davis profiles as the goal-line complement Cook never was, and Cook’s 195-pound frame plus a heavy 246-touch workload last season leaves legitimate injury risk. Eric wants at least 15 percent exposure before Davis’ price spikes once beat writers start noting a two-back committee in early-July practices.
