Nick Bosa controversies timeline: Every major off-field moment that made headlines (Image via Getty: Nick Bosa)Nick Bosa's girlfriend Ella Ailiff just dropped a new modeling shoot on Instagram, and right on cue, Joe Burrow's girlfriend Olivia Ponton showed up in the comments. This time it was a simple "I miss you," but don't let the brevity fool you. These two have been doing this for months now, and at this point, it's less a one-off comment and more a running friendship playing out in public, one Instagram thread at a time.Olivia Ponton's "I miss you" comment on Ella Ailiff's post reveals their bondAiliff, a model who's been dating the 49ers star Nick Bosa since late last year, posted her latest shoot and got an instant reaction from Ponton, who's linked to Bengals quarterback Joe Burrow.​Ella Ailiff​The "I miss you" comment might read casual, but it fits a pattern that's been building since earlier this year, when Ponton left a string of excited comments on one of Ailiff's bikini shoots, and later again when she cheered Ailiff on from a scuba trip halfway across the world. These two clearly aren't just exchanging pleasantries. They actually keep tabs on each other.Meanwhile, their quarterbacks are having very different camps. Bosa is nursing his way back from a torn ACL and sat out Monday's practice with soreness, just one of several injury concerns piling up for the 49ers this preseason.Burrow, on the other hand, is staying typically private about his relationship with Ponton, though the two were spotted on the Bengals' practice field together after Sunday's session, low-key as ever.A friendship that predates this one commentThis isn't the first time Ponton and Ailiff have shown up for each other online, and that's really the point. Back in May, Ailiff posted a magazine shoot in a pink bikini, and Ponton didn't hold back, dropping multiple comments including "Holy crap Ella" and "My jaw is on the floor." A few weeks before that, Ponton was on a trip to Tahiti, documenting an underwater excursion at a coral garden, and it was Ailiff who showed up in her comments with an enthusiastic reaction. Back and forth, shoot after shoot, trip after trip, they keep showing up for each other. It's not a coincidence at this point. It's a rhythm.That kind of consistency is rare in the world of NFL WAGs, where public interactions between girlfriends tend to be limited to the occasional joint appearance at a game or a red carpet photo.Ponton and Ailiff clearly know each other well enough that a modeling shoot doesn't just get likes, it gets an actual reaction, the kind you'd expect between close friends rather than two women whose only connection is dating players in the same league.What makes this worth watching isn't the comment itself, it's the consistency. Ponton and Ailiff have quietly built one of the more visible support systems among current NFL girlfriends, showing up for each other online again and again, regardless of what's happening with Bosa or Burrow on the field.And with both Bosa and Burrow entering big stretches of the season, one working his way back from injury and the other staying tight-lipped about his personal life as usual, it's honestly refreshing that the girlfriends are the ones giving fans something warm to hold onto. Expect this pattern to keep showing up all season long, one comment section at a time.
