I think the best part of this for Brent is he gets the experience of sitting in offensive meetings with yet another great offensive mind prior to ever moving to an official position coach job.
He is going to be in meetings with Brad Scott, Weis, and Pat White. Add his time with Lane and TF, and Brent is building a strong resume/coaching tree. I look for him to be a P5 OC/QB coach within the next few years.
