This is true. OC's like Kubiak do not hang around long. Great Coordinators become HC's unfortunately. It would have been interesting to see Kubiak continue to work with Flacco and run our offense. However I like Trestman. He may not be a guru but he can competently run an offense. He has a lot of experience and has proven he can be successful on offense. Ravens played under some terrible OC's like Cavanaugh and Cameron. Trestman may not be a guru but he is experienced.
Many offenses that are supposed to be great around the league are getting off the line slowly. As Flacco builds chemistry with Perriman, Wallace and Moore the offense will get better as its parts work smoother with more reps. Last years Trestman's offense got better later in the season. Even with Aiken as its #1 weapon. So give the offense several more games. We have Stanley and Lewis returning. And every game and practice Flacco and his WR's/OL get that much more comfortable. Our Offense scored 27 points with 2 backups on Flacco's line. It will get better. Wallace, Perriman and Moore will get going. We have a RB returning that is special catching the ball. If Moore catches that ball we are not even talking about replacing Trestman.
Trestman can be successful. Is it really a good thing for Flacco to learn a new system? He is getting familiar with his guys and Trestman will hear his plea for more big plays. We have Stanley, Lewis and Dixon returning. Lets not drop the hammer on rookie Chris Moore. Without a young slot WR he is probably our best at fast early separation as far as I know of. And has never demonstrated problems with drops before. Offense has some cleaning up but is capable of big things with its speed. Give Trestman an opportunity.
