I don't think so. Ye of little faith in the team. Hardy is much taller than Sweed and he's a much bigger endzone target than Sweed. Did I mention how long of a stride he has? He's the new Plaxico Burress or Moss.
If anything we need a veteran if we trade Losman. Losman is no teacher to Edwards in my opinion but I think looking for a veteran QB is that way to go if we trade Losman. Even if we get a 4th round pick for him, I'd take it.
Also, we can change it up. Some kickoffs we will have McKelvin and others will have McGee/Parrish. We can really screw up opponents ST because of how different each of them run.
In term of flat out speed it's
1. Parrish
2. McLovin'
3. McGee
