Questions: Who wins the job – Burke or Froman? Which QB will emerge as the most consistent - and reliable - performer? Will either player be able to cut down on turnovers, a problem last season, and efficiently get the ball into the hands of Louisville's playmakers?
Outlook: Froman might have the edge because of his mobility and play-making ability. He also appears to provide the most on-field leadership and command in the huddle of the three main candidates.
Questions: Who steps up to replace the leadership Wood provided the past few years? Is redshirt freshman Mario Benavides ready to fill Wood's enormous shoes at center? Will JUCO Joe Evinger be eligible? Is freshman Kamran Joyer ready to step in an make an impact this season? Can either Jeff Adams or Greg Tomczyk protect the quarterbacks blindside at left tackle?
Outlook: This unit is critical to Louisville's success on offense, especially with a new quarterback under center. The Cardinals will miss Wood's leadership and Bussey's athleticism but there's enough returning experience and talent to piece together a solid line. But what about depth?
Questions: Can Louisville stop the run without Heyman and Grady in the middle? Are there any playmakers on the roster who can generate a pass rush from the end positions? Are JUCO transfers Joe Townsend, Malcolm Tatum and Tim High ready to step in and provide depth immediately?
Outlook: Walker and Jessen should be solid in the middle against the run but depth behind them is a major concern. Louisville desperately needs Rodney Gnat to step up his play and become a legit pass rush threat at end.
Questions: Is Karldell Dunning ready to lockdown the corner position opposite Patrick? Or will one of several JUCO transfers, including Preston Pace, win the job? Is Richard Raglin back to full strength? Can JUCO Terence Simien make an impact at safety? Or will C.J. Peake finally make an impact after a year off?
Outlook: If Preston Pace can adapt quickly Louisville's corners should be solid. The big questions reside at safety where Richard Raglin is coming off an injury and the Cards are counting on junior college transfer Terence Simien and a couple of true freshmen to provide depth.
Questions: Are they improved? Is there a reliable kicker on the roster? Is Chris Philpott, the presumed front-runner for both jobs, capable of handling both kick-off and placekicking duties? Will a healthy Trent Guy translate to improved numbers in the return game?
Outlook: Louisville's return game should be better with a healthy Trent Guy returning kicks and Corey Goetsche is a reliable punter who can change field position around. The biggest question - again - is with the kicking game. That question won't be answered until the bullets are live and the Cards need to split the uprights on fourth down inside the 30.
