I'm sorry...
1) I find it hilariously ironic that you think Buff is for fans that don't have knowledge about hockey.
Byfuglien is well respected for being one of the best NHL blue-liners by GMs and scouts, and yes I can actually say this since I talk to those types all the time as a day job.
Ex: I had one non-Jet NHL head coach recently joke that Byfuglien would be both awesome but terrible for his team since the guy can be the best player to have been on the ice for 55 mins of the game and than the worst for 5. He was exaggerating but he understood that it's the fans that dislike Buff that are being fooled by the 5 minutes rather than what he does through most of the game.
Note: I'm not using this as evidence that Byfuglien is bad or good. That would be appeal to authority. I'm just pointing out that your comment that Byfuglien is for fans that do not know hockey is just straight up wrong and if anything it's fans that tend to under appreciate the things Byfuglien does due to overly focusing on the big "whoops" moments.
2) I cannot take you seriously and doubt any will if you are spouting out stuff this excessively exaggerated rhetoric every time and cannot have a proper discussion on Byfuglien with true back and fourth. There are tons on this board that have disagreements with myself on what Byfuglien is and his true value, but I'll let you know that they can at least have civil discussions without just simply shooting out ridiculous statements without any sort of evidence whatsoever.
Byfuglien indeed has his warts. His defensive value, in suppressing goals against, is legitimately poor and even below replacement level this season. Despite these warts, last week when I checked he was still ranked in the top 60 (~35) for best overall impact relative to ice time for even strength minutes in the entire NHL for the 180 most commonly used defenders.
