Yes, Seattle def needs to upgrade LG & RT personnel. Plus, poor OL play by Seattle this year is partly a result of an unhealthy Iupati constantly moving in and out of the starting lineup. Same with Ogbuehe. With Ogbuehe, communication is probably going to be an issue. But Iupati needs to go because he's seriously limited athletically and cannot block in space. If defenses put a DT over his nose he can lock on and can be fine (exception, quick guys like Donald). The Giants made Iupati block LBs at the 2nd level, in space, and Iupati couldn't get a finger on them. And those LBs would make, or be in on, the tackles. So, as the Seattle OC, you see that but don't make any adjustments in blocking responsibilities or play calling??? Another example of bad scheme: 3rd down and long, and Seattle throws a 3-yard drag route to Hollister??? Some might say that's bad play calling or decision making. But Seattle does stuff like that all the time. At some point, Seattle coaches have to coach up the offense, if the defense does "this", we're going to counter with "that", and start taking what the defense gives, etc.No scheme can mask their poor O line paly.
