Georgia opens spring practice today, and all signs are the Bulldogs will be the next defense to jump on the 3-4 bandwagon, scrapping the standard 4-3 set for the leaner look preferred by new defensive coordinator Todd Grantham. That shift means a slew of position changes -- tackles moving outside to end, ends moving to outside linebacker, etc. -- but the biggest change for UGA fans is still the absence of former coordinator Willie Martinez, whose unit declined statistically from the previous season in each of his five seasons.
