What's this 'Spygate' I keep hearing about?

A former Rams player, ticket broker, and some lawyer have sued some NFL team for some alleged impropriety. I don't remember from my business law classes if a civil suit requires the defendant or respondent or whatever to prove innocence - unlike a criminal case which puts the burden of proof on the prosecutor - but where is this going to go? The Patriots of the Belichick era have already been tainted, and really, I think that's the most that the teams who lost to New England during the span can hope for. Marshall Faulk, for one, doesn't think anything will ultimately come of the pseudovestigation.
