We won't do any expansion for the forseeable future, especially not in the NEZ. We just redid the entire area outside the NEZ.
I'm going out on a limb and say you're completely wrong about this. LSU will add suites to the NEZ within 5-6 years, maybe less.
LSU has identified premium seating as the wave of the future. Alabama's BDS currently has the most suites and/or premium seats in the SEC and TAMU's Kyle Field will have the 2nd most after it's finished in 2015. Tiger Stadium will have the third most in 2014, just ahead of UT's Neyland. So the NEZ is prime territory for expansion.
It's all about the Return On Investment (ROI). And premium seating gives athletic directors the most bang for the buck in terms of athletics infrastructure.
