First, would be to enclose the NEZ could add maybe 8k. Other ideas would be to add a 2nd to the East stands... costly! but could add 15k. Last idea and not even sure if its able to be done but would be to add a third tier to the SEZ. which could add maybe 5k.

With the NEZ it would cut in to the practice field, so Tech would have to make-up for the space lost in expanding that in another direction. Anyway you look at it, it will be costly.
