Gruden & Jaworski Bringing "Tension" To MNF Booth?

I didn't see the open of this week's Monday Night Football on ESPN, but I was made aware of a heated exchange between commentators Ron Jaworksi and Jon Gruden via Deadspin scribe Drew Magary's Twitter account.  Thankfully, someone had the good sense to upload said exchange onto YouTube.



Are the MNF producers encouraging Jaws and Chucky to bark at each other, or is there some legitimate animosity?  It's hard for me to tell from that clip alone.  But there have been multiple tweets popping up with claims that the tension has lingered throughout tonight's broadcast of the Minnesota-Chicago game.  My opinion?  I don't know, I'm hopped up on antibiotics and steroids and watching wrestling.  My Giants are eliminated, it's hockey season.  Leave me alone.
