It's pretty easy to point out the San Francisco 49ers have several concerns and holes they need to address this offseason, specifically through the NFL Draft. And the ones that don't will probably face that problem in a year or two's time. One, the offensive line, is what NFL.com analyst Bucky Brooks tabbed in his latest mock draft as the Niners' top choice to address this April. But Williams also indicated he's not mulling retirement just yet, meaning the 49ers could lessen this priority when the draft rolls around. That said, Brooks' draft creates some unforeseen problems that would smack the Niners in the face, if they were to come true.
