The Giants secondary already includes James Bradberry, Adoree’ Jackson, Darnay Holmes, Jabrill Peppers, Logan Ryan, and Xavier McKinney. Hence, don’t expect Rodarius Williams to find significant playing time (at first) if he makes the team.
He’ll likely be a situational defensive back and special teams component, which is totally fine. Williams will need to develop at the professional level and will probably need to take a decent amount of time to do so.
Time will tell if he eventually becomes a concrete aspect of this defensive backfield, but for right now, he’ll need to be patient and keep putting the work in as a young rookie.
