If the team decides he's finally at a point, going into his sixth NFL season, to step up and be a contributor, I'll be pulling for him. Seems like a great teammate.
But if the team likes Perry and Davis, I don't think it's worth losing either of them for a guy who has 19 receptions over five NFL seasons (most of those coming in his rookie season) and who turns 29 in December. But sure, if Kirkwood is far enough ahead of either or both of them, he will have earned it, just not certain that's the best outcome.
