​We are closing in on fall camp and it’s time to talk about the worst part of football: injuries. Relatively, Texas has benefitted from injury luck during the Sarkisian era, not losing any irreplaceable player for the season. That being said, there have been preseason injuries the past two seasons(Andre Cojoe, CJ Baxter). Considering that, I figured it’s time to highlight the six players I believe Texas can’t afford to lose if they want to realize their ultimate goal.This goes without saying. If Arch Manning is not on the field throughout this season, Texas is not winning a National Championship. Now, that doesn’t mean KJ Lacey can’t perform in a game or two if called upon, but it can’t be in major moments. Manning fought through an injury last season and performed well down the stretch, but Texas needs him fully healthy if they want to finish the season on top.AdvertisementAdvertisementAdvertisementIf Arch Manning is on this list, the man protecting his blindside should be as well. Goosby is one of the best OTs in the country and Texas needs him healthy and on the field all season. He’s dealt with a shoulder injury this offseason but seems to be healthy heading into fall camp. Again, there are players that can fill in sparingly, but noone that can match Goosby over a full season.Many have circled linebacker as the position of concern for Texas this season. One of the sole reasons it’s not a major issue is Rasheem Biles. The Pitt transfer is coming off an 100-tackle, 4.5 sack season and figures to repeat this season. If Biles goes down, not only are freshmen LB to step up but the versatility of the defense drops drastically. Biles is a chess piece for Muschamp and losing him would lower the ceiling considerably.AdvertisementAdvertisementAdvertisementThe other position where depth is a concern is safety. McDonald and Derek Williams Jr. are the favorites to earn the starting jobs. Jordon Johnson-Rubel, Kobe Black and Xavier Filsaime will factor into the rotation as well. Like Biles, McDonald has elite versatility and without him, the secondary loses its leader and main communicator. Poor communication can lead to consistent busted coverages, a championship killer.There are many reasons Cam Coleman was regarded as one of the biggest portal pickups this offseason. The underrated one is his gravity. Every time No. 8 steps on the field, the defense will have thier eyes on him. It’s likely many defenses will commit a cornerback and a safety to him throughout the game. That gravity is as important as anything for this Texas offense and without it, the offense could fall back into stop-and-start drives.AdvertisementAdvertisementAdvertisementFinally, the most obvious statement ever: the best player on the team cannot miss major time. Simmons is the Jeremiah Smith of defense. He’s the player teams commit extra resources to stop, which opens up opportunities for other players. Losing him would make the job of opposing offensive coordinator
