Outside linebacker Lawrence Timmons, the No. 15 pick in the draft, agreed Sunday with the Steelers on a five-year contract that could be worth as much as $15 million and guarantees him $8,053,000 in bonus money. Timmons became only the third first-round pick in the April draft to reach terms and the first in the upper half of the draft. Previously, the only first-rounders under contract were 49ers offensive tackle Joe Starkey and Bears tight end Greg Olsen.
