NFL mock draft 2015: SB Nation's 2-round mock goes wide receiver, defensive line for 49ers

SB Nation's Dan Kadar posted his latest 2015 NFL mock draft, and he elected to go with a two-round mock this time around. In assessing the San Francisco 49ers, he has the team drafting a wide receiver and a defensive lineman. Dan mocks them Arizona State wide receiver Jaelen Strong in the first round, and Florida State defensive end Mario Edwards in the second round.

In going with Strong in the first round, Dan looks at the potential that the team will not select Dorial Green-Beckham due to his off-the-field concerns. This results in DGB dropping to the Seattle Seahawks at No. 31. The wide receivers before the 49ers include Amari Cooper (No. 4 - Raiders), Kevin White (No. 11 - Vikings) and DeVante Parker (No. 12 - Browns).

Dan likes a guy like Edwards because he can plug right in on the end of the 49ers 3-4 defense. Even if Justin Smith does not retire, he likely only has one more year in him, and the team also released Ray McDonald. The team needs to invest in the line to provide more competition for young guys like Tank Carradine and Quinton Dial. Edwards would be one such player.

Whether or not the 49ers end up releasing wide receiver Stevie Johnson, wide receiver is not the only position in play in the first. Defensive line makes sense, and even offensive guard could happen. Can we narrow the 49ers needs down to those positions? Some would suggest cornerback as well, but I am not seeing it. The 49ers have generally not invested high picks in pure cornerbacks, and they have a lot of young options that could potentially move into the lineup. We don't know what will happen with Chris Culliver and Perrish Cox, but if they re-sign even one of them, that could push the position further down the priority list.

What positions make the most sense in the first round for the 49ers?
