The contract that Rams rookie OT Jason Smith signed Thursday is worth a maximum of $61.775 million over five years, with $33 million guaranteed, a league source told NFL Network’s Jason La Canfora.

Linebacker Rey Maualuga, a second-round draft pick by the Cincinnati Bengals, has agreed to a four-year deal, according to a source. Also Wednesday, the Vikings signed offensive tackle Phil Loadholt to a four-year deal.

Picks in the top two rounds are agreeing to contracts with greater frequency now, but still a majority of the top picks unsigned.
