It's certainly easier to make this thread off the back of Colton's worst game of the season, if not his career. He is what he is, a middle of the pack punter with momentary glimpses of poor and brilliant play. He's only given up 162 return yards this season, I think that's probably been by design. Kicking slightly shorter, to the sideline quite a bit. Best execution of which was Week 1 against Devin Hester.
He's not got a booming leg but he's a pretty decent directional punter. That helps him kill the ball instead of giving up touchbacks (only 2 this year on 57 punts).
There's an interview with Danny Crossman in the archives for the John Murphy Show, it's worth listening to. They talk about asking him to execute a lot of different techniques and that they've put a lot on his plate this year. He seems pretty happy with the job Colton's been doing.
Long-term, I think he's replaceable. His RFA tender will be somewhere around the $1.9m mark so they could grab a UDFA and let them battle for it in camp. He's not bad - could be both better and worse.
