Darren,
It depends on what types of sports photography you are looking to build a portfolio for.
You won't see that kind of editing in newspapers and so if you are looking to shoot for an agency or directly to the papers then your first example would be preferred. Colour, density, exposure, crop/rotate and nothing else. However, if you are looking to shoot PR or corporate sports photography, or advertising then a more creative approach works and you might see a more contrasty/"HDR look" in images.
If you are going to put a lot of editing effort into the second example, and it is more PR/commercial than editorial (it wouldn't be appropriate at all for news images) then you should also be looking to remove the distractions in the background. You could do that with less DOF but you could also clone those out the blue and yellow objects. Clearly you would be hoping for a better background and if you were setting up a PR shoot then certainly you would have selected somewhere else.
Whilst it isn't directly related to your question in the initial post I do have to say that the crop by
@Joeturner11 really doesn't work. You wouldn't ever crop a player close to the action in half on the edge of the frame - they either need to be fully in or fully out of the image. To include the out of focus two spectators in (one of whom is also clipped) again is a poor judgement in my opinion especially in preference to the remainder of the cropped player. It also appears to have either introduced a slant, or not corrected it as in your edit. Your focus should be entirely on the action for this kind of image.
