I voted no, thinking it would be an unnecessary distraction.  But then I looked at the records of the teams of the years they did the show:
Season 1:  Ravens:  10-6 (2001)
Season 2: Cowboys: 5-11(2002)
Season 3: Jags:  9-7 (2004)
Season 4: Chiefs  4-12 (2007)
Season 5: Cowboys 9-7 (2008)
Season 6: Bengals  10-6 (2009)
Season 7: Jets 11-5 (2010)
Season 8 (cancelled for labor concerns)
Season 9:  Dolphins 7-9 (2012)
Season 10: Bengals  11-5 (2013)
Season 11: Falcons  6-10 (2014)
Six teams finished with winning records.  Four teams with losing records.
So maybe it isn't really something that has a big effect on how a team can prepare and what sort of season they will have.
That surprised me a bit.
Maybe I'm a little more up in the air about it.
On one hand, I'm not big on taking a risk that it COULD be a distraction.
On the other--I'd love to watch them prepare for the season.
I'd say I'm more "undecided" right now.
