You could argue zero of the San Francisco 49ers’ rookies are primed to make a big impact in 2015.
The first-round pick, Arik Armstead, is a 21-year-old project who has played football full time for just one year.
The second-round pick, Jaquiski Tartt, is a safety on a team that already has two Pro Bowl safeties.
And the third-round pick, Eli Harold, is an outside linebacker on a team that has three starting-caliber outside linebackers.
None of the Niners rookies are likely to start. But a few of them—including an undrafted free agent—can earn significant roles in specific defensive packages or offensive personnel groupings or special teams units.
