It's a near 10% swing, but if you really want to look at the data, Horne would be trending MUCH better. Otah missed a completely season and only played 4 games his final 2 years. Horne just had his healthiest season yet. Otah's was also a reoccurring knee injury while Horne's were more random. It's really apples to oranges IMO.
Honestly I think the comparison was just thrown out there for theatrics and just proven wrong. No big deal.
