I personally think there is a huge difference between the 2013 NFL Draft and the 2012 NFL Draft. For starters, last year was a way more interesting class with RGIII, Andrew Luck, Trent Richardson, Doug Martin, and Russel Wilson. But this year's class is pretty interesting with Luke Joeckel, Geno Smith, Marquise Goodwin, Desmond Trufant, Sharrif Floyd, Eddie Lacy, EJ Manual, and Tyrann "Honey Badger" Mathieu.
One major difference with this year's class is that this group is a little more diverse in position than last years'. I have a feeling Geno Smith is going to be similar to Russel Wilson in this Draft, but will be picked sooner. It also seems as if EJ Manual and the The Honey Badger are underestimated in this Draft. Last year, I don't think anybody was really underestimated except for Wilson. Trent Richardson is pretty much like Eddie Lacy this year. Although they are not the same back and Lacy may be picked later, they are pretty similar in skill.
In conclusion, this year's Draft is different from last year's, but not as we may think. There are not as many exciting names this year, but they will still be great.
