This is a good point. I, too, want Barney to succeed and to exceed the Pipeline years if possible. We all want a fantastic O Line. It's not about Barney, it's about the results. I don't care whose name sits next to the "Offensive Line Coach" title as long as it's a prospering unit. If it fails, it's time to make a change no matter whose name it is we're changing.
The one time I spoke to Coach Gilmore I found him to be very open, engaging, pleasant - a lot more approachable than Bo, for example. I wanted Gilmore gone not because of Gilmore, but because our WRs couldn't catch the ball (or hold onto it as they ran down the field untouched).
Barney has been accomodated with a number of quality OL commits in the last three classes. If he can't get it done over the next 4 or so years then it may be time to move on. Having said that, I like the combination of Barney and Garrison, and am looking forward to a productive year from the OL.
