Yep, totally inexcusable, and ultimately comes back to coaching. Mack let's them play too loose and undisciplined, and it bites them in the butt. This was exactly what I was afraid of, in the past when they've choked they've had lots of penalties, turnovers, sloppiness, and stupid decisions. Mack better adjust and reel 'em in.
Stupid turnover and unnecessary penalty this early doesn't bode well for the horns.
