San Francisco 49ers GM John Lynch explains why key veterans were let go, and the importance of Brock Purdy’s contract extension.

"Even though we kind of warned our fans, I think that's a tough pill to swallow, even if you hear it's happening," Lynch said on the latest '49ers Talk,'" via NBC Sports Bay Area. "I think it spoke to how good our roster was. We had a lot of talent on it, and we had acquired a lot of talent and accrued a lot of talent."
