No. you couldn't say the same thing about every CB on the market. That's why I asked the questions that I did. Questions that you intentionally ignored because you know that to answer them would detract from Murphy-Bunting's "shine" that you're putting on.
Murphy-Bunting had 9 Missed tackled on the season. His missed tackle numbers are 5, 16, 6, and 9 since he entered the league. Including 3 in the SB that Brady took them to. Missed tackles for a DB are a HUGE red flag for Belichick. Belichick has a quote that he's known for in regards to DBs. (I'm paraphrasing because I don't have the book handy) "Give me a DB who can't tackle. What am I going to do with him?"
You say his "coverage skills" make him a good player but you can't tell me whether or not he's better in Zone or Man. He only averages a little more than 5 PBUs a season. He's only getting 1.5 Ints per season.
