For now, Hollins is fourth on that depth chart. But if he keeps improving, if he shows that he can be more than a No. 4 receiver who also covers kickoffs and punts well, then maybe the Eagles won't have to sign another veteran receiver to a short-term contract next year, or the year after that. They could just count on Hollins, while he is still on his cost-effective rookie contract, to fill that role. In a salary-cap world, that sort of succession plan is the goal for every team: no need to spend more money on a position you'd already thought you'd addressed, no need to burn another draft pick because a previous one didn't work out.
