Losing Ben Johnson and Aaron Glenn will NOT be the end of the Lions ... at least, that's what Calvin Johnson is saying -- as the Detroit legend tells TMZ Sports he's confident his squad will recover.
The 15-2 team, of course, was poached by the Bears and the Jets this offseason ... when the duo nabbed Ben Johnson and Glenn for their vacant head coaching positions.
