The only one remotely close to what's happened was Belichick. He fizzled in Cleveland before going to NE and doing what he did. Allen has had a total of 5 years HC experience. It's not his first rodeo. What we see is what we're gonna get with Allen. Coaches rarely change substantially from year to year, and usually when they do, it doesn't go well. I think Loomis is just trying to get us to drink the Kool aid. I'm not buying what he's selling at this point.
Allen, and Loomis, may well prove me and many of us wrong, but we've been watching football long enough to know the odds are slim of that happen
