A few videos. Quality isn't great, as one might expect. Watching, I see the potential for Sey to have been graceful, but she, like pretty much every American at that time, lacked the refinement, extension, and polish of a truly great gymnast. Sey is very much a Parkettes gymnast.
1985 worlds optional beam
1987 compulsory floor (I think this is US nationals, but not 100% sure)
The entire 1986 US nationals broadcast, if you are so inclined. It's terrible, just one hour to cover men and women including EF, plus juniors Phoebe Mills and Kristie Phillips. WAG starts around the 26 minute mark. We only get Sey in AA on beam and floor and in both cases partial routines. We also see Sey on EF bars. MLR is commentating, so you've been warned. Her mullet is quite the thing
