Every single team has people talking about unproven players that they are optimistic about in the offseason. The same argument you made in support of Remmers was probably said about Nate Chandler last year. He had a good finish in 2013. I think people were saying PFF has positive grades on him. In this league, everyone on the outside is going to doubt you until you indisputably prove yourself. If you are not a sure thing, people are gonna point that out. And even when you do start playing well, it takes awhile for people to notice.
I'm not totally sure that this is true. I can definitely see your point..you do have an argument..guys that command double teams are valuable. But it is a league where getting to the QB is becoming everything. Pass rushing is an art form, and I dont think there are a lot of guys that are great pass rushers from the DT position. My real point is that its hard to come up with an easy answer for this.
