​SOUTH BEND – Welcome to an impossible exercise for a showdown of two Top 10 teams that carry serious national championship aspirations on what might be one of those nights for Notre Dame football inside Notre Dame Stadium. Here we pinpoint four players to watch, but four is nowhere enough. Eight might not be. Even a dozen might still be too small a number. There are big-time players capable of making big-time plays across each sideline in this one. The quarterbacks. The linebackers. The running backs. The interior lines. Heck, even the head coaches should be ones to watch. We see you, Mario and Marcus. Who do you track in this one? Who don’t you? Keep your head on a swivel while trying to see this guy and that guy and those guys. Let’s at least start with these four and go from there. You’ve been warned. There’s talent everywhere in this one. Who will deliver? UM, ND 411: Notre Dame football vs. Miami | How to watch, game timeAnalysis: Showdown with Miami will require vintage CJ Carr for Notre DameNo. 1 MIAMI HURRICANES (8-0)DB Omar Thornton (0)The step up in competition seems to suit the Carver Ranches, Florida native just fine, thank you. Same goes from stepping from the college football shadows into the white-hot spotlight for a program barreling toward a possible return to the national championship game. The 5-foot-11, 201-pound Thornton spent two years in anonymity up there at Boston College, where he produced at an All-Atlantic Coast Conference level. Thornton played in 23 games with 14 starts with the Eagles, where he tallied 111 tackles. Last year in Chestnut Hill, Mass., he made a team-high nine stops against Notre Dame. So, he knows the Irish. Coming off a season high eight tackles against Clemson, Thornton has been relatively quiet the last three weeks. He’s made only five stops, including just one last weekend at North Carolina. The former high school linebacker has found ways to affect games other than tackles. He’s second on the Hurricanes’ 28th ranked defense in tackles for loss (6.5) and first for quarterback hurries (five). He has three sacks. He handles his business on the back end of the defense and handles business at the line of scrimmage. WR Malachi Toney (1)Toney announced his arrival on the college football big stage not so subtly last season as a true freshman when the 5-11, 183-pounder from Liberty City caught 109 passes for 1,211 yards and 10 touchdowns. Guess what? He might be better as a sophomore. Seriously, why isn’t Toney getting more Heisman Tropy love? Through eight games, Tony has tallied 73 catches for 1,027 yards and 13 touchdowns. He averages 14.1 yards per catch. He averages nine catches for 128 yards per game. He gets game planned by every opposing defensive coordinator yet still finds room to roam in secondaries and down the sidelines and, most importantly, into end zones. Everybody knows Toney’s going to get the ball, but nobody knows how to stop him on an offense with a plethora of
