Just to add to the discussion, I want to look at turning close losses into wins. Last year we lost 3 games against top 20, 10 win teams by one possession. Just a handful of plays go our way and we had a 10-3 season ourselves, but that's what ifs. Looking at Iowa history, however, there is a pattern of a season of close losses preceding a successful one.
In 2001, 4 of 5 losses came by one possession, and the 5th was by 9 to a Joe Tiller-led Purdue team. In 2002, we convert those tight games, going 3-1 instead.
In 2008, all 4 losses came by a total of 12 points, going an overall 2-4 in one possession games. The following year, we go 4-2 in those games en route to an Orange Bowl win.
In 2014, we go 3-4 in close games including some snoozer wins over UNI and Ball State, and losing the final 3. In 2015, again we reverse that trend, going 5-1, the only loss being the B1GCCG.
These numbers are hardly concrete or predictive, but with such a young team last year that got a lot of experience and showed flashes of brilliance, I'd argue that the experience of losing close games may be key in learning how to win them this coming season.
