Mark knopfler is an awesome very classy player! But even he would tell you as a modest musician that being the best finger picker might raise some questions! Especially when you see guys like Tommy Emmanuel and Thomas zwijsen. But yes I agree he is a great player with great feel. Which is the most important.
he's one of my fav guitarists, but to say he's the best at finger picking is a little bit ignorant, or misguided. This is not even finger picking anyway lol. But I still love his style of play
