Notre Dame had a calm offseason, a blessing when dealing with a physical sport played by 18- to 22-year-olds. Despite the recent attrition in the receiving corps — headlined by Monday’s reports of a season-long suspension for Irish sophomore receiver Kevin Austin — the drama, concern and unknown has not exceeded its normal level. Rather, the last eight months have been smoother around the program than usual. It’s just that all the unexpected issues have come at one broad position, with Austin joining junior tight end Cole Kmet and junior receiver Michael Young on the sideline, the latter two each recovering from a broken collarbone.
