Depends of the time-span.
But to each his own. I had my first ammy MMA fight at 18, and now 8 years later I've had 7 ammy fights in total
(and 3 amateur boxing bouts, and a lot of wrestling/grappling matches)
but I never had the ambition to become a pro, so I took it easy, as a hobby, one or two fights a year, then one year without a fight, etc etc...
If a guy had 7 fights in one year, accumulating as much experience as possible so he can have his first pro fight without ring/cage jitters, it's different that if he had them in 3 or 4 years;
and in that case if you original goal was to turn pro, it's indeed long but not in a positive way.
I have some friends who were really good, in a good team, hanging in there with the pros in sparring matches and didn't even bother with ammy competition before turning pro.
So I don't know what to make of this comment from DC...
