serious?
Yes seriously. Last year some teams adopted the arm in arm stance to show unity with the kneelers. Players not brave/stupid enough to join in could virtue signal while sort of avoiding potential backlash. All the articles today are describing the arm and arm stances as solidarity in protesting Trump. Arm in arm was never about standing and showing respect. It is also self evident, if your arms are linked you can’t very well put your hand over your heart can you?
