I don't remember no one having any special credentials neither in striking nor in grappling...I could be wrong though, and I know you have quite a knowledge in MMA history as well, so feel free to correct me.
Regarding Goodrige - I don't believe he was as good of a striker as he was strong and his strikes were heavy.
Probably one of the first really brutal fighters in MMA history.
For instance, Leonardo Castelo Branco was BJJ Next Gen at that time, highly regarded...
Edson Carvalho [BJJ/Judo], the infamous Death Master, was hespected in the Brazilian scene...
Nick Nutter had a short career, Hammer House dude...
Mikhail Ilyukhin, sambo champ, pioneer @ RTT, b4 Fedor...Experienced vet, tricky like hell...
Many sambo dudes in all these tournaments, but they didnt have many opportunities to shine due to them being Eastern European and the limitations of the NHB/ValeTudo market back then...
Personally, I like to study those forgotten fighters...
On a sidenote, Igor also fought in Pride: Valentijn Overeem [powerful striker who developped a legit ground game, in particular a sound leglocks arsenal] , Carlos Barreto [BJJ giant from Carlson´s...had the physical tool to develop a lethal striking but was always a lil bit too hesitant...], Yvel [good striking indeed... he even developped a decent ground game later on, pulling some nice armbars...]
Big Daddy actually had a boxing [amateur] background, decent striker but his fight IQ was not that great...
