Hmm...I see. It isn't like I think Ike can reach S tier though. Heck no, he simply can't match up to characters such as Meta Knight, etc.
For my first example of a sign Ike has potential, look at how good this expert Ike player does against an expert Snake.

He didn't win that first match, but still, it was really close.
Eh... Wifi/Online is kinda hard to use as a solid example for an offline metagame. The reason being that even in nearly lagless environments, there's enough of a delay that it causes significant enough change to game play where it's just not comparable to offline game play. Also, for online play, you can have HUGE input lag without there being a noticeable lagging/slowdown of the game (so it might take you over half a second for Ike's jab to come out, even though the game doesn't appear to slow down any).
Many characters become better or worse over online play. Ike is generally considered better online because the restrictions on reaction timing are lower, allowing him to punish/hit people in circumstances where they would likely not get hit or be able to more reliable punish Ike for attacking. Characters like Wario are drastically reduced in how effective they can be used online. He's such a frame intense, reactive character (at least for me anyways), that reaction restrictions online hamper a player's ability to crucially react with Wario to what the opponent does, hence he can't do things like weave in and out of their grasp very well.
If you have more videos, you can go ahead and post them and we will look over them, but try to find ones that are not over online, as they may suggest a slightly distorted match for either side.
Also, date of a video has a HUGE impact when considering how closely it resembles the current metagame. Over the span of even 3 months, you would be surprised how much gameplay/strategies for characters can shift due to new ideas/better options being found for situations. Most videos from 2008, even between pro's, are not accurate nowadays in understanding the current metagame.
