Roger vs Gordon in the gi. Does Gordon score before mount?

Same two names, different universe: grips, collar danger, pressure passing, and a scoreboard people would argue about for years.

From local garages to world-class academies.

We lost 6 students in one month before we had retention alerts. Last month the system flagged 4 at-risk members and we brought 3 back with a single nudge. That's $450/mo saved.
