Surprised some people are having problems with Kitna and Hill. In a lot of respects they are very similar. They are both backup QBs, they both have great surrounding talent, and have the potential to put up good games. Shaun Hill has just been doing it longer this year than Kitna. If they both had good matchups then I would consider starting Kitna over him because he's thrown half as many times as Hill in the past two games yet manages to put up insane points. If he got 50 attempts like Hill then he might really blow up.
Of course, there's a reason why Shaun Hill has been so reliable everytime he starts. Every full game he has played he has thrown over 30 times. These are the pass attempts during his 6 full games as a starter: 45, 43, 54, 32, 50, 47. He's gone over 300 yards 3 times in this time span and had 4 games with multiple TDs. Any QB who throws this much will have serviceable fantasy stats. He's not talented but in the end, he gets you fantasy points because of opportunity and that's all that matters. I expect the Patriots to score on them easily and quickly meaning that the Lions have to play catch up and pass like crazy to stay competitive like always. It's not a matter of a defense being good. If a team is throwing 50 times, you can only limit a guy to so many yards and if the Patriots go on a tear against the Lions, we might see a situation like Cassel vs Broncos.
Anyway, the difference between Shaun Hill and Kitna this week is a very stingy saints defense that is ranked 3 against the pass, gave up 7 TDs and 1 game over 300 yards vs a very lenient patriots defense that is in the bottom 3 and gave up 18 TDs and 5 300 yard games. Saints defense is much better than the Giants and Lions so I don't think it's a given that he will continue the streak and I don't think he's done enough to make him a must start stud. And with the exception of studs, I probably wouldn't start any QB against them. You can argue that the Saints faced bad QBs but they did face Roethlisberger and Ryan and they certainly look for real. At least this is my rationale for picking Hill over Kitna. In a week with comparable matchups from now on though, I pick Kitna. I just don't factor in hot streaks as highly as some other people and rely on more on QB skill, matchups, surrounding talent, and likely game scenario to figure out who to start and sit. Who knows, Kitna might actually be the first to blow up with a 300 yard multi td game against the saints.
