Foster took advantage of the opening and earned the roster spot rather than backing into it. He is still a depth option behind stars, but a strong camp and preseason give him a credible chance to be the next-man-up.
Strengths: Earned an initial-53 spot, made preseason plays, and demonstrated that he can respond when opportunity expands.
Weaknesses: Limited path to targets behind four high-level receivers, so his early value depends on special teams and injury contingency.
