The 49ers probably didn't intend to re-sign Rock Ya-Sin, but it won't matter with the Lions signing the free agent anyway.
One of the major themes for the San Francisco 49ers this offseaosn has been to get both younger and cheaper.
Looking at the flurry of departures -- either via trade, release or free agency -- the Niners are taking the first painful steps of accomplishing this. In contrast, San Francisco's free-agent pickups and re-signs have largely been to bolster special teams and the back end of the depth chart.
Speaking of the depth chart's back end, the 49ers inked veteran cornerback Rock Ya-Sin to a one-year deal heading into 2024, ideally having him as an experienced body to guard against injuries to the two starters, Charvarius Ward and Deommodore Lenoir.
Ward already inked his own free-agent deal with the Indianapolis Colts, while Lenoir and 2024 rookie Renardo Green are penciled in as the two first-team options heading into 2025.
The soon-to-be 29-year-old Ya-Sin won't factor into the Niners' equation, however.
Lions deny 49ers the chance to re-sign Rock Ya-Sin
It's not surprising to see Ya-Sin clear the first wave of free agency, especially after he appeared in only 13 games for San Francisco last season, starting none of them and primarily contributing on special teams.
But the former second-round pick from the 2019 draft has plenty of experience, including 79 games played (39 of which were starts) with the Indianapolis Colts, Las Vegas Raiders, Baltimore Ravens and eventually the 49ers.
So, to bolster their own hopes of remaining atop the NFC pecking order, the Detroit Lions opted to add Ya-Sin, according to a report from NFL Network's Mike Garafolo:

There's no indication the Niners had interest in retaining Ya-Sin, who wasn't viewed as much more than a depth piece when he originally signed in the Bay Area a year ago.
That said, San Francisco's cornerback depth chart was already thin to begin with, and the free agent's departure only highlights that.
The 49ers now hope for either some bargain-basement free-agent pickups, which isn't out of the realm of possibility, or they'll turn to April's draft with the aim of landing some impactful rookie talent.
