The player who gets mocked to the Los Angeles at pick 19 the most often is UCLA edge rusher Laiatu Latu. According to Mock Draft Database, Latu gets mocked to the Rams in 25-percent of drafts, right after the Bengals pick J.C. Latham and before the Steelers pick Amarius Mims.
Who are the “consensus” mock draft picks for the other three NFC West teams?
Arizona Cardinals - WR Marvin Harrison, Jr.
I don’t always put the ‘Jr’ respect on somebody’s name unless everyone does it like “Ken Griffey, Jr”, but Harrison necessitates the extra two letters and punctuation because everybody knows his dad.
