Griffin, Nelson or Merriweather?

I just read over at scout.com that BB and Pioli were VERY impressed with Nelson at his pro day today. Apparently, he had a VERY good work out. Almost "FLAWLESS." The article says that BB and Pioli were so impressed that they will stay in Florida to work him out one on one tomorrow

This will be something to watch on draft day.

I like the idea of a trade up, but i dont want to package both of our 1st rounders. If he is there at 19, then i can see us trading up, but two first rounders represents too much value for us to blow on a guy that could go top 12.
