I like Vaccarro, but this is a deep safety class, and I think he is definitely a reach at number nine overall.
Keep in mind that safety is a position that is devalued on draft day.
I hope that the Jets address the pass rush at number nine with a guy like Jarvis Jones or Bark Mingo. The Jets lack of a pass rush really killed them last season, they have good talent up front with Wilkerson and Coples, but you need a pass rush off the edge to make the 3-4 work. (look at Ware in Dallas, Suggs in Baltimore, etc.)
If they do that, they could draft a safety like Eric Reid (SS) from LSU or Tony Jefferson (FS) from Oklahoma in the second round.
I found this really interesting and in depth big board from Sportsmasher.com which has a lot of detail on the to 70 in the draft, definitely worth a look:
