First of all, you need to identify what your team is. This team is currently not constructed to be a pass first, West Coast offense. We don't have the personnel at almost every position to run this. Flacco is not a WC QB. He's a strong armed gunslinger in the mold of Favre. He believes in his arm, sometimes to a fault. We don't have an agile zone-blocking line. We have road graders. Our backs are not speedy scatbacks. They are one cut and go types that can (if they choose to) pound it between the tackles. We didn't have fast/agile TE's that can run around underneath and create mismatches and then make something happen after the catch. Waller just can't catch the ball consistently enough and Maxx wasn't on the field. And....we have a full back. WC offenses do not use a FB. What I am saying here is that the first and most important thing you can do to help Joe Flacco is to turn this offense into a system that fits him and not try to make him fit a system that goes against virtually everything he is.
1: Coaching Improvements: This is already a fail because you didn't improve in the first major area and that would be OC. So now you want creative position coaches? Huh? Last time I checked the RB coach wasn't calling the offensive game plan. I guess Harbaugh just eluded to what we are all thinking. He wants Marty's replacement already in house when we finally realize 5-6 games in the season that nothing has changed. I do believe we need a new WR coach. Our WR's can never seem to get open and when they do, they drop the balls that hit them in the hands. I can understand not catching a pass you need to dive or jump for. But no excuse to drop passes CONSISTENTLY that hit you in the hands. Dennis Pitta; despite the things he can't do, can do one thing extremely well. He reads zones and knows how to get open in that coverage. It seems that none of our Wideouts know this.
2: Better Offensive Line: Just drafted franchise LT, You still have Yanda who is one of the best in the game at RG, Wagner was pretty good overall at RT and is most likely walking. LG/RG was an iffy spot with Alex Lewis (rookie) and Vlad Ducasse (journeyman) being your best options. Lewis was a rookie starting next to another rookie and was playing out of position. I believe he will make a better RT. Yanda is supposed to move back to RG. I don't see anyone in house being a great option to go to LG which means two things. 1) You draft another rookie. 2) You sign a good veteran, but probably wind up paying a premium and keeping him a couple more years past his usefulness. At Center Zuttah was decent until this season while he was completely banged up. Bad back and ankle issues. His replacement might be on the team in either John Urschel or Matt Skura...might. You can't turn over the job of center to somebody that doesn't know what he's doing. The LT might be the most critical position on the line because of the job description, but the C is the QB of the line and is the one supposed to make all the line's protection calls. There is quite a bit of work that needs to be done here.
3) Healthier Knee & Chemistry: Well, unless we're Dr. "Bones" McCoy from Star Trek, there's nothing anyone can do about Joe's knee. It will heal on its own time. I am also wondering what the deal was with his throwing shoulder and if that is still an issue. It clearly was affecting him for two games and perhaps it was a lingering thing from then on. The only thing Joe can do is workout and rehab as much as he can. As for chemistry, well, that's on Joe as well. How about hanging out with the guys on a voluntary off season mini passing camp?
4) Getting more Playmakers: Been hearing this for years yet we strike out in the draft and we don't sign premier guys in FA, instead we sign cast offs and guys at the tail ends of their careers. Keeping Aiken would be a mistake in my opinion and just repeating the past issues. There's nothing special about him. If you want a sure fire possession guy, bring back Boldin if he doesn't retire. THAT is a possession guy. He will make the tough catches. He will catch things that hit him in the hands. He will catch things you think he has no business catching. He's tough and he will run guys over. He is a redzone threat as well. Brandon Marshall if he becomes available is a playmaker. There are some question marks about him being healthy/motivated. I think playing for the Jets and a jerk of a QB like Cutler can certainly destroy your motivation and happiness. One thing Marhsall has proven is that he's a playmaker and he scores the football. The players will be out there, the question is if the Ravens will pony up what it takes to get them? As for the running back they want to add, I've said it before and I will say it again. They're looking for a Blount-type runner. Not necessarily to be the bell cow, but to be a red zone/short yardage/goal line pounder.
