It's all about deciding what is most important for the team in most cases. Lovie was all over D and horrible at developing personnel. That stagnated the O for years and we are still not out of it. When the drafting and spending is so blatantly lopsided a bias will show. Again, they have more tape and player history with guys currently on the team than we will ever have. They know secrets about players we will never know. For some reason they like Webb over Carimi. It may be medical, mental or simply execution they are seeing.
As far as blind trust is concerned, I have three and only three people.(None of them are in the NFL) I do know that IMO Webb is better than Carimi, just as I thought he was better than Williams last year. It's based on production and the feel I get from analyzing them.
