It's never a bad thing to get your name out there, hone your skills, get feedback on your experience etc by interviewing. I don't know much about Brian so can't really say whether it would be our loss or not. However, it is likely that from where he's sitting up close in the division, he understands what a mess Wrecks is, how disfunctional the owner is in forcing Tebow on the team for backpage headlines and in a pursuit to foist overpriced PSLs, and the cap difficulties the team allegedly is in. From a career standpoint, while you can't beat hands on experience, sometimes when there are so few jobs in your industry, it's better to bide your time, continue to build your reputation (or perception of such) than to throw yourself into the fire, already with 1 testicle removed (being stuck with Blutto), running the risk of ending up another sacrificial lamb in a dysfunctional, classless organization. Hopefully cooler heads than his agent who is fee-driven will reinforce this notion.
