I see no issue with looking at Murray. In the cap age, the roster is full of 1-2 year deals surrounding the core that eats up the cap. He produced when called on, while helping out at a Orlando area high school. Lots of bridge players in the NFL.
I suppose we're all different in viewing the team but I always wait until camp to view the progress of the roster with the Bills and Sabres. Who is securing a role/roster spot and who isn't. I get many fans are optimistic by nature. What's wrong with that ? Yet predicting failure with limited or no knowledge seems to be the new hip thingy these days in social media. Strange world.
