I'd be really intrigued by Dion Jordan at WLB. Remember that our GM and coach love LBs with long arms, and they need their LBs to be fast. Jordan might run a 4.4 at the combine, and if moved to LB he would probably have the longest wingspan of any LB in the NFL by a large margin. He also really impressed me a lot in press coverage. He looked Browner-like at it. While I don't buy Jordan as an NFL DE (too stiff, all he can do is rush the edge), he does have special potential as a blitzer. And while Jordan didn't play LB at Oregon, Kelly moved him around a lot and Jordan showed that he could make a difference when dropping back into the 2nd level. Honestly, would not be shocked if PC/JS had him rated insanely high at LB.
I did a little research on Alonso (spelled with an "s" it turns out).
He didn't look very fast in the clips I saw of him. Similar speed to Skov- he'll probably run in the 4.6 to 4.7 range. NFL draft scout (Rob Rang's site?) estimates he'll run between 4.62 and 4.86.
I liked what I saw though. He's got NFL size/bulk and is a good instinctive player. Not hard at all to see him being a good player in the NFL. Most teams don't value speed at LB as much as Pete does- so I think Alonso has a very good chance to leave the board in round 2. He just doesn't look fast enough for Pete though.
