The Athletic has live coverage of Clemson vs. LSU.Clemson coach Dabo Swinney rose to prominence and won national championships before the transfer portal, name, image and likeness and modern roster construction existed.New LSU coach Lane Kiffin in recent years has mastered building rosters the new way, heavily utilizing the portal and investing resources to attract transfers while dubbing himself the “Portal King” — though it has yet to yield any national title rings.On Saturday night, when Clemson and LSU meet, the two philosophies will clash. Swinney, who rarely used the portal until recently, fields a team heavy on homegrown talent while most of Kiffin’s major contributors started their careers at other schools. Kiffin’s team will not field any players who participated in NFL training camps against Clemson, a decision that came down late Friday night and is subject to ongoing litigation.Here’s a look at how each team’s roster breaks down.Notes: Snap counts, games and starts come from SportSource Analytics and Tracking Football. LSU’s potential additions of former NFL players are not included in this analysis. All recruiting rankings are from the 247Sports Composite. How Clemson was builtClemson thrived in college football’s pre-portal era, playing for the national championship four times from 2015 to 2019. Under Swinney, the Tigers recruited at a high level during and after that run (six top-10 classes in eight years from 2015 to 2022). The portal launched toward the end of the 2018 season but truly ramped up in 2021 when transfer restrictions — which previously required players to sit out a year — were loosened.As more teams tapped into the portal, Swinney stayed true to the philosophy that got Clemson to the mountaintop. But as the Tigers have slipped from national championship contention lately (Clemson went 9-4, 10-4 and 7-6 the last three seasons after 12 consecutive years of double-digit wins), that approach drew criticism.
