‘Holcomb has appeared in just 28 games in five seasons, but has been productive when given opportunities to play. Holcomb doesn’t have a great arm and limited athleticism. But he is a smart player who makes the right defensive reads and usually makes sound decisions with the ball. While he’s not expected to beat out Losman for the starting job, the Bills hope Holcomb will provide enough stiff competition to make Losman better.’
