Down to the last two unsigned West picks

The San Francisco 49ers have announced a four-year contract with first-round draft choice A.J. Jenkins.

That leaves the St. Louis Rams' Janoris Jenkins and Trumaine Johnson, both cornerbacks, as the only 2012 draft choices from NFC West teams without announced agreements.

The Rams' decision to trade down from the second and sixth overall choices lowered the stakes for negotiations. Some higher choices remain unsigned while agents and teams haggle over guarantees.

Even so, contract disputes aren't expected to infringe upon training camps to the degree they have in the past, if at all.
