2011 has been a season about overachievers and underachievers.
For those overachieving teams like Washington, Buffalo, Detroit and Oakland, there's reason to look ahead and anticipate success. Their fan bases have become reinvigorated, and things look bright as we near the second half of the season.
For those who haven't measured up to expectations, it's officially do or die.
We are nearing midseason, and 1-4 or 2-3 can become 2-6 quickly. Some of those teams' struggles are going to lead to regime change, potentially long before season's end.
This week we take a look at five coaches—including Jack Del Rio—who are sitting firmly on the hot seat.
