It’s possible that Trevor Davis could actually contribute as a receiver, but he hasn’t shown that is a going to happen in two seasons.
Eight total catches for 94 yards and a touchdown over that span.
Where Davis has shown some production is in the return game. He’s averaged 22.7 on kick returns and 12.2 on punt returns. Davis has actually been a pretty solid punt returner. Five of more than 20 yards in only 33 returns and a long of 65.
But it’s hard to keep a guy who only returns punts well on an NFL team.
