As mentioned Star Lotulelei (Utah) and Johnathan Jenkins (Georgia) are the two main NT's that catch my attention.
It is also a good year in the SEC for 5-Tech DE's. Bama has two 5-Tech type DE's in Dial and Square. Kapron Lewis-Moore from Notre Dame (6'4", 300) and Margus Hunt from SMU (6'7", 290) are interesting prospects there also. Hunt is also a world class discuss thrower and from Estonia.
OLB's and ILB's look good also.
