Not sure they'll address all of the needs people list.
CB for example... we have Gonzalez, Alex Austin, J Jones, M Jones, Wade, Marco Wilson all as guys who have played regular snaps for teams and (besides J Jones) are 25 or under. Then they have Isaiah Bolden from last year and Marcellus Dial from this past draft as more young guys I think they seemingly have shown some optimism on.
At FS, the combo trio of Dugger/Peppers/Mapu didn't hold us back last year. On paper there's certainly room for a true center field type, but they got by without one last year. And some of those CBs I listed above might potentially factor into the FS mix along with Bledsoe who they keep on keeping around.
LT is a need on paper, but in the big picture not sure they'll see the need to add someone. They seem to have Onwenu entrenched at RT at least for now, just to lock that spot down. David Andrews obviously is entrenched at center.
So what does that leave them at guard? Strange/Sow/Mafi/JAndrews/Robinson are all guys they've drafted in the last 3 years. That's a good amount of youth to compete for the 2 G spots.
And at LT, they have Okorafor/Anderson/Wallace/Lowe/Wheatley competing. Not the most inspiring group, but Wallace in particular seems like someone they specifically targeted and felt was undervalued because he got pushed to RT at Penn State. They could definitely sign a guy like Leno or Donovan Smith to provide a more solid veteran option, but feels like they really want to give Wallace a shot to win that job. And seems like they're confident that if that fails Okorafor can play the spot not so terribly that it kills the entire unit and wastes a year of development for everyone.
At those positions, I think they might just want to just let the young guys compete for spots. Maybe it backfires and they get poor play, but to be fair it's pretty much the same group they had on defense last year and it's not like it killed them. The LT on offense is more concerning, but seems like they've hitched their wagon to who's there.
The RB spot is one I see more likely to address. They just lack bodies there. At those other spots they have options to compete in camp. At RB they don't even have enough guys to bring into camp really. They almost have to add there.
