The calendar makes it tempting to cast aside anxiety about Chargers first-round pick Mike Williams being unable to participate in offseason workouts.
But the concern here is that the Chargers originally hoped Williams would be back in a week and on Tuesday announced the receiver would be out until at least training camp.
The diagnosis of “mild disc herniation” in his lower back means there is more to this injury than a first day of OTA muscle strain. Any timeline for return being extended – even in June – is a potential red flag.
