10 people are suppose to be fighting that's 5 fights at least. So 5, 5 minute fights (with the break in between) is a good half hour of entertainment and I'm sure everyone will be there an hour/ hour and a half. (accounting for down time in between fights)
There should be enough room they have a boxing night there once a month and there has been as many as 25-30 people attend those. So if I can single handedly sellout Sullivan Brothers Gym then I'm asking to box there for FREE from now on.
