Great Stuff Marvin, and the .Nut boards are imploding!
Agree on Garoppolo, he's struggling with the full playbook. And so is the rookies and 2nd year players too. Keep in mind the WR's and Arby's have to handle the full playbook too now above and beyond what they were doing in that 5-0 run. Getting the OLine and WR's healthy is going to be big going into KC. Brieda developing as a pass receiver gives Garoppolo another option similar to McKinnon and I'm pretty sure Kyle can get *another* Brieda (an undrafted RB) next year to back up Brieda if McKinnon can't make it back 100% from injury. Back to Jimmy, I think the way he's such a fast learner and his incredible off schedule talent, I would say give him till mid season to master this offense to the 80% level.
Agree on the WR's. We need more speed, and we do have it. Pettis is one of the faster receivers in the draft. I don't think he'll be trying out for the Olympics in Tokyo in 2020 but he has the speed to scare DB's enough to give him a cushion and break man to man coverage, it's just that he needs to run the correct routs and get acclimated to the NFL level of speed and competition.
Pass rush, agree. Deforest will be our designated pass rusher (either rushing from the inside or at LEO) we got nobody else. If they can just get a guy that can be a credible pass rusher - this defense will be formidable. *IF* Blair, Day, and Pita develop - conceivably they can move Buckner back inside where he's - as you said - a monster. Otherwise, unfortunately you are right - we won't get one via trade and will have to wait till the draft.
Linebackers, with Reuben back, that should improve. There were a couple of 3rd and mid range where the pass rush forced Stafford to dump off and if the LB's could have tackled the pass receiver prior to the first down marker, it would have been a 3 and out. The west coast offense has always had problems with teams that have excellent linebackers. Who can forget the New York Giants eliminating us from a 3 peat because of their excellent linebackers. With Reuben and Fred, we have the linebackers to slow down Fat Andy's offense. (which is a more stone age version of Kyle Shanahan's offense)
Taylor and Kittle - they are going to be a good combo. Focus on Taylor, Kittle will kill you. Focus on Kittle, Taylor/Goodwin/Garcon will score on you. In other words, I'm not worried about Taylor. He's healthy and his back surgery shouldn't have affected his speed and agility. If defenses are clumping around the middle of the field and smothering the in-between the hashmark routes, that opens the outside zone run to the edges and also misdirection play-passes. Kyle will adjust his offense to counter the counters of the defensive coordinators.
I say wait about another two games before the offense hits it's cruising speed. 49er are averaging almost 20 points a game, and they are still in the takeoff stage, wait till they hit cruising speed - assuming everybody gets healthy on offense - Kyle will blow Fat Andy's offense out of the water.
