RB1 is 30 years old. And I'm not expecting more than 2 or 3 games out of RB2. He's not part of the equation at all. Yes, RB is a huge need. And they have a chance to get a good one. On O-line, the Saints need better depth, but the same starting O-line as last year, expect maybe LG isn't the worst thing. I'd hardly call that a huge need. Backup O-line? Yes, that's a huge need.
And, yes, the Saints have needs everywhere. But with Jeanty and Kamara, with Miller as RB3, they could have a very good run game. I would definitely take that.
