I think Martin Tyler has had his day on Sky. They're loyal to him presumably because he was with them from day one, so maybe he's a bit of a 'national treasure' in their eyes, but some of his comments these days are cringingly bad. I thought Clive Tyldesley was very harshly treated when ITV "relegated" him, because he's okay in my book. He's cleared off to CBS Sports now. A far superior commentator to Martin Tyler anyway.
