How was Keenum allowed to play?
Incompetence, that's how. Plain and simple. The incompetence was spread over multiple levels. The NFL, the officials, the Rams, the Ravens, even the players on the field are culpable.
Somebody, ANYBODY should've stepped up for Keenum and nobody did. Even most of us beer-swilling knot-heads recognized the situation immediately and called for Keenum to be removed from the field. I guess we, as fans, care more about a player than his "brothers in arms" out there on the field.
I'm actually more disgusted with my favorite team over this than the fact that they stink, as per usual. I have to believe all the constant talk about having each other's backs is just that, talk. Talk is freakin' cheap...
