Bill with any of the HOF QBs from that era has a similar career. Brady with any of the coaches those QBs had, has a similar career as them. With the caveat that Brady took a long time to become elite and I'm not sure another coach would have had the patience.
Combined, they did things neither could do alone, or with anyone else. But given Bill's defensive prowess he could generate the same level of success in a wider variety of situations. Mostly because the number of coaches that can consistently field a top10 defense over a 2 decade period is basically a class of 1.
Twitter said the extra guy was Hamlin, which makes sense since he's a 5th string DB and not normally on the field. Which is all the more reason not to change, too many backups for a 1/50 chance.
