I thought Lawson had a pretty low ceiling. He'll never dominate offensively, but he's got some pretty good vision and has shot the ball a lot better than most people thought he would. No reason he can't be an above average starting PG some day.
If he is underrated now it's because he was so overrated after dropping 55. He's a good player that's not arguable but I think that Milwaukee's hot streak has had a lot to do with Bogut finally being completely healthy also. And he's the only one who plays in the East (when is that no longer going to put an asterisk next to a team/player's name?)
Getting Salmons has also been a key too. He is averaging around 20 points since being acquired. Stackhouse gives them veteran leadership too. Jennings 55 pt game gave people the wrong idea of him. After that a lot of people compared him to Allen Iverson which is wrong because he's more of a pass 1st PG.
