According to CBS' Jason La Canfora, the 49ers have "expressed to others" that an Alex Smith trade is "effectively complete."Any potential deal cannot be finalized until the new league year begins on March 12. La Canfora does not know the acquiring team, but lists the Chiefs and Jaguars as "two teams that make sense." Both NFL.com and Yahoo Sports have reported in the past three days that the Chiefs were Smith's most dogged pursuer. Although his arm limitations were as evident as ever last season, Smith would be an acceptable stop-gap option in Andy Reid's West Coast offense. Smith isn't expected to fetch more than a mid-round pick.
