I've agreed with you in my first post that Evans won't be a top-drawer defender, but not being a top-drawer defender doesn't mean he isn't worthy of starting in the first team. Ronny Johnsen was not a world class defender like Stam was, yet he was Stam's main defensive partner during our 1998/99 season along with Henning Berg. Evans may not be up there with Ferdinand, Vidic, Bruce, or Stam, but he looks better than O'Shea and Silvestre and has had a better playing career than Brown, up to now, even though Brown had a higher ceiling than Evans.
As others have mentioned, there are several reasons why Evans isn't a top-drawer defender by now. One of those reasons that I highlighted in my first post is the fact that he doesn't have the natural instincts of a central defender that Smalling or Jones have (which is why I think those two will be ahead of Evans, eventually). However, like Gary Neville, if Evans continues to work hard and iron out more of his weaknesses, he'll have a successful career, here. This is the point many of us, here, are trying to articulate. Your posts seem to indicate that you think that Evans won't be a key contributor to this side. I think otherwise.
During the time when Jones and Smalling are developing their game, still, Evans will be key in keeping composure and providing leadership in this side, IMO. As I said before, he may not a world class man-marker (decent, though), and his in-the-box positioning is a bit suspect, but his other strengths convince me that he can be a key player for us in this side like Brown and O'Shea were even if they weren't regular starters. As I said earlier, if he keeps continuing to improve himself and continue to work hard on the training ground, he will become a key player for us even if he's not going to be a starter, here.
Don't regret the post, Mauzindark. It's nice to read differing views around here rather than the same old, same old. It's not like I 100% disagree with your post. You have made some good points, but you have come out as being too pessimistic, to me.
