Why? They expected to be us at one time.
The 2013-2015 seasons included winning the division twice, a conference championship, NY6 buzz, and a 10-win season during a rebuilding year with a Freshman QB. I genuinely thought that was going to be the new norm and it really helped alleviate the sting of being a conference left-behind. It turned out that those seasons were just Doc's flash in the pan.
The success reminded me a lot of what NIU does in the MAC. They don't win it all every year but they're always in contention, year-in and year-out.
And to be fair, maybe wanting to be like NIU is probably unreasonable, too. I just looked at their wiki page -- In the past decade, they've won their division 7 times, conference 4 times, and went to the Orange Bowl. Their bowl record (2-7) is comparatively horrible to The Herd's but I could live with their overall level of success.
