It's a natural reaction. Fans and media seem to think it's the big name playmakers that will come in and turn a team around. Without thinking about the innerworkings of a football team, these people seem to think a big name QB or RB from college can come in and instantly turn around a decrepit situation as if they were a superhero.
Why is it some teams seem to be able to plug anyone they want in at running back and get a 1000 yard rusher, while the Browns have only had one in eight years with a bunch of different backs? It is no coincidence that Browns also throw a patch work offensive line out there every year.
This year the Browns have spent a ton on the line, but could you imagine if they got one more stud? I keep hearing that Steinbach could move to LT, but if a guy dominates a position are you really best served by hoping he will be adequate somewhere else? Kevin Shaffer has played LT his entire career. He was a pretty good LT when he played for a left handed quarterback. That would make him a weak side LT, going against probably a bigger, slower seven technique DE. He is no longer responsible for the QB's blind side and will get matched up with generally the lesser of a teams two DE's. (guys like Julius Peppers generally line up on the strong side). This makes Shaffer a better RT, provided he can get the "reversed" footwork down.
