Who was in charge of getting TL's match-ups for this? If you were to go by this chart, TL would easily be one of the best characters in the game. He has much more than two bad match-ups, and he certainly isn't weak against Zelda. There was a thread in the TL boards recently about this match-up, and it was generally agreed that the only problems were Zelda's Side B and her KO power, which can both be avoided by air-dodging and using zair at the right time. This match-up really isn't hard for TL, it could even be an advantage. See

TL has a disadvantage against Falco, Marth, MK, and Pikachu. There are others that are debatable, but these four are clearly against TL. Anyone who needs a reason should just look at the characters, it should be obvious.
Some of the match-ups on the chart are really outdated, you should consider just deleting some of the entries. Most of the links that were posted for each character are from April or earlier, and the match-ups then clearly aren't the same as they are now.
