I'm discounting beating any teams but those I listed. If we're getting 6-8 wins, it's coming from that group - with perhaps 1 surprise home win elsewhere in the schedule.
You mentioned we have a shot against Maryland, Iowa, Michigan State, and Indiana earlier? Any given team on any given day and all, but those aren't games you can expect we'll be competitive in a year from now. You seem to think that everyone's losses will be devastating and our gains will be game changing. Every team loses players every year and replaces them - every team's underclassmen get better each year. Most teams' underclassmen have a year of legitimate practice going into the following season, rather than uncontested walkthroughs and drills without any defense being taught - so, we're even at a further disadvantage there. Most schools in the conference have strong 2016 classes coming in to both compete for time and provide strong practice competition for the starters, too. You're talking about three of the top ten teams in the country this year and saying that a team ranked 282nd is going to top them next year after they've finished their nonconference slate. Be serious. It's like saying "St. Francis is going to have a shot against Villanova, UNC, Louisville, and Kansas in a mid-season matchup next year - just you watch".
This season, we play 3 of the 4 worst teams in the conference twice, whether by chance or design, and only 4 of the 9 are on the road. If we get that sort of schedule next year, which is unlikely, we'd be looking at taking all the home games and 1-3 of the road games against that group to get to 6-8 wins. Or 0-2 of the road games, plus one surprise win at home against a middle-pack conference team.
A more realistic expectation would be winning 3-5 conference games and doing better in the nonconference schedule. Finish with 12-14 overall wins, and build on that going into 2017-18 with a nearly identical roster (hopefully with a couple of strong 2017 recruits to replace transfers from the bottom of the depth chart).
Now, that may or may not include a coaching change. If EJ is somehow retained for next season *and* he manages 14+ wins *and* he turns over two bottom-roster players to bring in two 4* or better recruits... he may just survive to coach the following year with a short extension. Otherwise, we bring in a new guy who can hopefully preserve the top players and open up space in the roster for a strong first year of recruiting with the 2017 class.
