OK it has had some time to seek in, let's look at the fantasy implications of Cutler leaving Denver for the Windy City:
Jay Cutler - Expect a dip in numbers, at least in the short-term. For starters, the Bears lack the wideouts and the offensive line he had in Denver. Secondly, Lovie Smith and his staff are not a pass-first offense and even if they adjust a bit it will be gradual. Cutler threw for 4,526 yards last season, don't expect him to sniff that number in 2009. On talent alone, he's still a top fantasy QB heading into next year, but before the off-season shakedown I would have argued him as top five passer.
Matt Forte - Forte's value immediately goes up with a capable signal caller at the helm. I'm not expecting his yardage totals or receptions to see a huge hike, but it's hard to imagine that he won't get more opportunities to score touchdwns and in fantasy that is what matters most. Forte is a borderline top five pick at running back for 2009 and a sure-fire first rounder.
Devin Hester - Hester really started to show signs of his big-play ability during the 2008 campaign despite the fact Kyle Orton struggled to get him the ball deep. Cutler has the arm to battle the winds of Solider Field and will be able to deliver accurate passes deep for Hester to cash in on some big plays. Still, this trade will likely lead to Hester being overvalued by many come draft day. I look at him as a solid WR3 for your fantasy team with some serious upside.
Greg Olsen - I have always been a fan of Olsen's, but for the most part he has not lived up to hype and has been inconsistent as a fantasy tight end. However, with the Bears likely to open up the passing a bit more with Cutler and the lack of receivers on the team common sense suggests that the big tight end will quickly become one of Cutler's favorite targets.
Kyle Orton - It is not a given that he will start in Denver and there appears to be a QB battle brewing with Chris Simms. One thing is for sure, Josh McDaniel's is going to be a pass-first coach and will utilize a system quarterback. The Broncos will likely look for a more long-term option in the draft, but for the 2009 season Orton has the opportunity to be a nice grab as a backup quarterback. If he wins the job outright, it's safe to assume his fantasy value will see a boost.
Denver RB's - With Mike Shanahan gone, so to are the days of banking on the Broncos' backfield for fantasy success. Youngster Ryan Torrain and incumbents Selvin Young and Andre Hall will be fighting for their roster spots as newcomers Correll Buckhalter, LaMont Jordan, and J.J Arrington are all going have a role. Until somebody steps out in the competition owners should try to avoid the headaches altogether.
Brandon Marshall/Eddie Royal - Marshall has bigger problems to deal with, but the loss of Cutler coupled with his off-the-field drama has me dropping him down a tier in my rankings. The guy has huge talent, but now he also carries with him a lot of question marks. Royal will also see a dip in his numbers with the departure of Cutler. Both receivers are still worth owning, but the gamble is going to be there so draft accordingly.
