In general, sports teams typically evaluate their players' performance and potential during the offseason, pre-season, and regular season games to determine the starting lineup for the upcoming season. Coaches and team management also consider injuries, player availability, and other factors when making decisions about the starting lineup.
For a college football team like the Huskies, the starting lineup will likely be influenced by the returning players from the previous season, as well as new recruits and transfers. The coaching staff will evaluate each player's strengths, weaknesses, and overall fit within the team's strategy and game plan.
It's important to keep in mind that the starting lineup can change throughout the season based on player performance and injuries, so while there may be a projected starting lineup at the beginning of the season, it's not set in stone.
