Seattle have a decently good QB that could help them over the hump in 2005.
If George would be there that long, which he may or may not be (he would be 37 by then).
Let's say that Jeff decides to accept that trade instead of hold out for FA (like the video said). After looking at the 96 Seahawk schedule, he would have had an extra bye week to learn the Seahawk offense. However, they probably stick with John Friesz for five weeks after the bye (he lost to KC, won three in a row, and then lost to Detroit in Week 12). In Week 13, with Seattle at 5-7, George makes his debut against the Raiders. They lost that game in OTL with Mirer, but with George, they win to up their record to 6-7 (still in the playoff race).
In Week 14, though, they end up running into an Orange and Blue buzzsaw. George makes it closer, but the Broncos still win and wrap up home field. After that, they win two of their last three games and end up 8-8.
In the off-season, George probably decides to stay since they seemed to be making a committment to winning (they wouldn't have that extra first-rounder from the Mirer trade, but they still trade up with Tampa to get LT Walter Jones). Besides Jones, they bring in DT Dan Saleamua, LB Chad Brown, and DB Willie Williams (they don't need to sign Moon in this world, though). They also draft RB Corey Dillon in Round 2 (Chris Warren is going into his FA year), LSU CB Denard Walker in Round 3 (they don't get Shawn Springs in this world, and they need more DB help), and So. Carolina WR Marcus Robinson in Round 4 (Brian Blades is 32 and on the decline).
In OTL, they were 8-8, but they lost several close games, including both games against the division-winning Chiefs and one against the eventual World Champion Broncos. They also lost to a bad Saint team in OT. With George at QB and Dillon at RB (who gradually replaces Chris Warren as the year goes on), they win 10-11 games, make the playoffs, and really shake up the AFC playoff picture depending on which games they win. They probably also make the playoffs in 98, and Dennis Erickson doesn't go to Oregon State in 1999 (and discover Ocho Cinco).
