I would think that Seattle will likely take him if he's available in the 2nd round. And could well be in that handful of prospects that we'd be comfortable with taking in the low 40s to 50 range when looking to trade back. Seattle is notorious for that, and it doesn't appear there will be much likelihood of a really good talent slipping to 32. The draft kind of looks like it hits the first real drop off at around pick 20. Maybe even sooner. So I would think the team would be inclined to trade back as they so typically do.
If I'm looking at traits that Seattle has seemed to covet, then Jake Fisher is going to fill a lot of check boxes. The fact that he's being downgraded/doubted and plays in an unorthodox system is probably more of a plus in Seattle estimation than it is a negative in the groupthink NFL draftnik circles.
Athletic, long, nasty, criticized, yet very quietly, anonymously and significantly valuable to his teams' success. A guy who is going to be passed over repeatedly on draft day. Sounds exactly like the kind of prospect at any position that Seattle falls in love with.
When I look at the typical top 10/15 offensive tackles on these lists, I don't see any one player in that group that ticks the Seahawk's kind of guy checklist as much as Fisher.
