Obviously chairbacks take up more room than bleachers...but it would be great if the city would turn the LB into a 43,000-45,000 seat chairback stadium.
Louisville was one of the first to build a 98% chairback seating stadium in 1998 with the opening of the 42,000 seat Papa John Stadium:
Having mostly sellouts for 12 plus years because seating/capacity was limited...UL was able to start up a season tix waiting list...including new premium seating areas...which lead to their 12,000 seat expansion a few years ago.
Imagine a LB with 42,000 blue seats?
Limiting capacity for UM games and even LB games will help raise more booster $$$$ and more higher priced season tix sales (vs relying on $5-$10 specials to sell so many tix).
Sellout the stadium before Game 1....that should always be the goal for any program...and limited capacity while offer much better amenities (chairbacks), it would be a win-win for city and team. (Life expectancy of the stadium would be extended for decades if they did this).
PS. For the mostly bleacher sections of the LB, they don't have bleacher backs do they? (i.e. just the bench seating...no back support)
