Player Ratings - Should we be worried?

How long can KU continue to win with Vick and Newman performing at such a profoundly pedestrian and mediocre level? What can you say about Devonte'. He is doing everything this year for KU that Mason did last season. Svi has had his share of down games (Kansas St. and Texas Tech and especially Washington) but overall he has been solid for the most part. Udoka took the Iowa St. game off but has been as consistent as anyone and at a high level. Lightfoot gives all he has and does some nice things but is not a true 7th man at this point. We need more from the 7th man. Garrett started out great and finished non-conference play on a 4 game slide. He picked it up again when conference play began but has been sub=par the last two games (way sub-par). Ideally you would like a 6th man with better numbers than Marcus but he is decent. Vick was arguably our 2nd best player in non-conference play and he had a great game against Texas in the 1st Big 12 game. Since then he has been streaky with poor games against the better teams. I am a little worried about Vick. But the real issue for this team is Malik. Malik had his breakout game against Iowa St. (weak competition relatively) and is back to being way sub-par. Malik's level of play right now is just about what you would like to see from a 6th man. We are missing a solid 5th starter right now and that needs to change.
