As a Lions homer and an owner of Kitna, KJ and Roy, I feel compelled to point out that the Lions have not won at Green Bay since 1991 and have had some dreadful showings there in that period. Here's my take on playing Kitna this week:Reasons to play Kitna: (1) He is guaranteed to be the starter; (2) He had his best game of the year in week 3 against GB (342 yards, 2 TDs, 1 INT); (3) the Packers continue to be a nice matchup for opposing QBs; and (4) now that KJ is done for the season even the minimal running game that did exist is no longer and Kitna will likely throw even more than usual. Reasons not to play Kitna: (1) He is a lock for at least 2 turnovers -- 11 of his 19 INTs have come in the Lions' 6 road games; (2) the OL was terrible to start with and now is playing new guys (some just off the practice squad) because the starters are injured; (3) without KJ, Kitna no longer has his safety outlet and Cason/Harris are unlikely to fill the void; (4) many of the Lions, and Roy Williams in particular, looked like they were thinking about their offseason plans during most of last week's game; (5) the Lions are traditionally poor @ GB; and (6) Kitna is just not good enough to rise above all of the Lions' problems.Getting back to the original question, Kitna is certainly a viable starter because he will have the opportunity to put up points in a promising matchup. That said, I would look elsewhere if possible (and especially in leagues that penalize for INTs or fumbles) because there are just too many other things wrong with the Lions to allow Kitna to make the most of this opportunity.
