Him, Carlos Lastra, Doug Des Autels etc are all those guys that have talent, but just not enough, they just don’t have it “all.” The skill is there, but they’re still just not good enough, and not marketable for core skateboarding. However, they’re so damn marketable with younger kids, it makes up for what they’re lacking as far as skill which is why they fit in so well with the PG rated companies like Revive.
John Hill is the only one out of all those guys that from a purely talent standpoint, could have actually made it in skateboarding, and was going to, but didn’t help his case by shitting away all his sponsors back in the day. That’s why he started doing YouTube, because no actual skateboarding companies wanted to deal with his bullshit anymore and was out of options. (I.e leaving in the middle of trips, not getting along with anyone, things like that)
So to answer your question, I think if Revive land didn’t exist, Giger could probably get a few decently reputable sponsors, but I doubt he’d ever get his name on a board for one.
