If you're going with the run heavy offense, then spending a premium pick on a LT makes even less sense to me. I'm fine with building the O-line but I don't think you need to spend the #2 pick on it in order for it to perform well.
They tried pass first at the beginning of this season and failed mostly due to the offensive line not being able to support the time they need to stretch the field.
Regardless of the adjustment, I don't think they want to be dependent on the run. I really think in the end that want to be a balanced team that has the ability to force a team to pick their poison, and that really does depend on a versatile offensive line more than a particular dominance at any skill position.
No doubt they won't go into next season thinking they can implement a spread offense right out of the gate, but I have no doubt that they will continue to implement a more complete passing attack as the team progresses, and this includes building a more dominant pass defense that isn't so dependent on the defensive line.
Not that I'm in the camp that believes the have to draft Matthews or Robinson. But just considering where they want this team to go and ready for the future, I think they will have to draft a guard and tackle if only for development purposes.
That said, there's really no way of saying who they draft or if they do pick a WR like Watkins. I believe that they could draft one or more of a DT, OLB, CB and FS in the first round to create a tremendously positive impact on the defense. I wouldn't be horrified like last season if they did draft Watkins, but that's only because of his actual strengths fitting the team's needs vs. Austin.
In the end, I think a lot may depend on what their options are for trading down. And there will be a lot of options for improving this team's defense and offense dramatically, to include that of drafting an OT and OG early.
