Yeah, I'm a huge soccer fan and they are all trying to maintain bubble leagues but it gets harder the more people involved. Soccer has 20 men rosters or smaller on game day with 11 on the field. There are a few coaches and medical staff.
An NFL team has a 46 man roster on game day with many coaches and staff to support them. During a game day there are around 100 people just standing around together on each side of the field.
Football is going to take a lot of work and effort but the owners and NFL organization are definitely doing everything in their power to make it happen because they want money. The NFL is a different kind of beast compared to MLB or NBA.
