Excellent post, Badol, and I agree to a certain extent. You never know when rookies make a huge impact in year one. The chances are rare, but it does happen. Someone like Mike Evans might not put up huge numbers, but what if he's an excellent redzone threat? Turn a few of those field goals into TDs last year and we probably make the playoffs. The same with ASJ.
I favor addressing the line via free agency, first and foremost, because they can help us out the most this year. Our rookies will need a year or two of grooming, but we should be ready for a playoff run that's lasts five plus years after this season.
