Three things: Seahawks-Broncos

Three things to watch for in the Seattle Seahawks' preseason road game against the Denver Broncos at 9 p.m. ET:

1. First-team offense TD: The Seahawks have yet to score a preseason touchdown on offense with Tarvaris Jackson at quarterback. Shaky pass protection, dropped passes by Golden Tate and a failure at the Minnesota goal line have not helped. The first-team offense did sustain a 15-play drive against the Raiders, an improvement from the preseason opener. I'm interested in seeing who Jackson targets on third down. His 17-yard pass to Mike Williams on third-and-5 against Minnesota stands as his lone pass for a third-down conversion. He threw incomplete to Justin Forsett, Zach Miller and Doug Baldwin on three others. A 6-yard completion to Forsett came up short. This is not a huge deal. We're only in preseason. But it's something to watch.

2. Backup running backs. Starter Marshawn Lynch will not play. He's resting a sore ankle. That could leave additional opportunities for Forsett and Leon Washington. Both appear worthy of getting playing time this season. Washington's surgically repaired leg is closer to full strength now than it was last season. Rules changes on kickoffs will diminish Washington's impact in that part of the game. It seems to me the Seahawks should make an effort to get more from him on offense.

3. Draft choice on bubble. After two drafts with Pete Carroll as head coach, the Seahawks have more players selected under him (17) than they have remaining from the combined draft classes of Jim Mora (four) and Mike Holmgren (eight). Most 2011 draft choices appear quite likely to earn roster spots this season. One player, fifth-round choice Mark LeGree, faces stiff competition. Rookie free agent Jeron Johnson has had a strong camp and has done more during preseason games. The Seahawks have quite a few young prospects in the secondary. Will any of them catch our attention with big plays in this game?
