Talib's actions were unacceptable - especially when he is claiming it was an accident. Pretty sure the odds are slim that you are going to try to poke a guy's helmet, and accidentally poke him in the eye - and with excessive force at that. That kind of stupidity can jeopardize someone's career. He should miss at least the remainder of the season, as it is plainly obvious to even my coworker who is a Denver fan.
The hit on Teddy I am split on. While he did come in quick with his shoulder lowered, he also appeared to be trying to avoid excessive contact once Teddy went into a slide. The penalty was probably justified, but a fine might be a bit much. Either way, tough call for me. As much as I don't like Minnesota, I would hate to see a guy like Bridgewater have his career cut short. Maybe it is due to me getting older, but I hate seeing injuries regardless of the team.
All the above said, I am also agreeing that something should be done about these QBs taking advantage of the contact rules. After the hit clay put on Kaepernick a while back, it was obvious that players are taking advantage of the rules. If a player takes off running down the sidelines - they often will step out right before contact to draw the 15 yarder. Some will act as if they are going out of bounds, defensive player lets up on persuit, player stays inbounds and has lots of room to run. A defensive player is bearing down on a scrambling QB, they slide right before contact to draw the flag. There should be more review of these things to consider whether contact was avoidable or not. I'm not fully sure how you deal with the tiptoe ballet dancers down the sidelines, but it is aggravating to see them gain extra yards because they can't be tackled without a 15 yarder tacked on.
