NFL mock draft 2015: What has free agency meant for the top of the draft?

The second week of free agency is upon us, and that means 2015 NFL mock drafts are slowly starting to shake up. While free agency will impact a few picks, it generally does not have a monstrous impact. A few teams will find impact players at previously much needed positions, but even that does not mean a team should avoid a given position. For example, the Minnesota Vikings acquired Mike Wallace, and the Miami Dolphins acquired Kenny Stills. Both are very solid wide receivers, but that does not preclude either team from going wide receiver in the first round of the 2015 NFL Draft.

SB Nation's Dan Kadar put together his latest mock draft, and he has both the Vikings and Dolphins adding wide receivers, going with Kevin White and DeVante Parker, respectively. Kadar had the 49ers going with a defensive line pick:

15. San Francisco 49ers: Arik Armstead, DE, Oregon

The 49ers may have signed Darnell Dockett, but he can't be considered a long-term fixture at end in San Francisco. Armstead can be that player. Armstead is a perfect scheme fit, coming out of Oregon's 3-4 defense. When he stays low, he has the power to knock offensive linemen around with ease. He's quick in short areas and would be a big asset in the run game. Just don't overlook cornerback here after the 49ers lost Chris Culliver and Perrish Cox.

The 49ers added depth over the weekend, and starting wide receiver Torrey Smith last week. Smith might make wide receiver a little bit less of a draft concern, but even that does not mean they won't go wide receiver in the first round. Some would argue cornerback is a serious need, but the team could very well decide to wait a couple rounds to find a cornerback.

In reality, this leaves the 49ers with several options in the first round. Whether they use pick No. 15, or make a trade, they could go cornerback, wide receiver, defensive line, or potentially even offensive line, and it would make some measure of sense. The team has holes to fill and they have the picks to do it, but they are not being boxed into a corner for a particularly specific position. I think it ends up being defensive line, but there are arguments for multiple positions.
