From what I remember, they have plays/picks and projections mapped out a month ahead of time. They have their own power ranking system, figure a spread, and compare their spread, to Vegas' spread, use stats compiled so far, injuries and other news and make a play. The more these things match up, the more they like the play.
Factor in the Bears have the worst offense:
**31st ranked passing offense thus far (completing less that 53% of their passes),
**30th ranked rushing offense
Factor in the Bears have the 31st rank defense:
**16 worst pass defense (giving up more than 60% completion percentage)
**Ranked LAST in Rushing defense giving up 4.5 yards per carry.
The pass defense would be WORSE but teams only have to run on them. Also add on that rumors are swirling about Juron being fired... I think we all thought the Bears wouldn't be this bad, and I'd switch my pick too.
