Love Sammy. However, I'm big on building defense first, before anything else. Also, without a long-term QB answer or a real viable running game, Sammy would be wasted for a few years. He'll have great plays, sure, but the Raiders won't be optimizing his talent because he won't have help on O.
Clowney or Mack would be ideal, in my opinion. Trading down might work, but it all depends on their gameplan with that and who they're after.
Agree with you on Sammy being under-utilized at first. My fear is that Clowney AND Mack would be off the board at 5. Hell, Sammy might be too and then we draft Bridgewater. Teddy might be a great pro, but I've waivered on him quite a bit.
I'd rather build the team and have a foundation in place for a young QB to step into rather than get the young QB, then build. Our defense was respectable the first half of the year...lack of depth and pass rushers eventually caught up with us.
Trading down could work if Reggie likes Carr and feels he'll be available later in the 1st. Why not acquire more picks...we need the depth and young talent.
