We need a miracle at QB to get more than two wins (Wagner and UMass) and even then 4 (Indiana and Illinois) is probably the high water mark.
Massey has Illinois at #87 and USF #100, Navy #94 and ECU at # 112 so why not shot at beating last 3 if can get Indiana at # 60 in an away game? If can compete with #60 Indiana away why not also Tulane #81, Houston #79, Cin. # 61 and Temple # 66? Seems like lot of "average or worse" FBS opponents to play and get some wins.
UConn had historic bad defense in 2018 but not like some of UConn's opponents this year weren't also really, really bad last year (only 6 of 129 FBS schools gave up over 40 points per game and only UConn at 50.4 gave up over 50). UMass # 126 @ 42.9, Ill. # 123 @ 39.4, ECU # 120 @ 37.3 and Houston # 118 @ 37.2.
My point is that UConn plays a lot of mediocre teams (based on last year and Massey early season estimates) and of all the "misjudgements" about 2019 season (based on recency bias) the most likely is that UConn's defense will be super bad again in 2019. Just being really bad (like 2018 SMU @ #110 at 35.3) gets UConn in a lot of these games.
As far as miracle at QB, Pindell got stats but scoring was 22.2 per game (including FCS game with 56 points) or # 111 so isn't exactly world beating (especially given how many low rated defenses UConn faced last year).
My point here is that HCRE2.0 has the plate set for big improvement in win total from last year based on: 1. Hopefully unrepeatable bad defense (based on team age/development, change DC, some new guys with experience/ability), 2. lose Pindell but not much scoring anyway with guy who couldn't pass, 3. OL should be solid and running game should be solid.
Not saying get way more than 4 wins, just that the pool of potential wins are much more than the 4 you mentioned (although the 1st 2 of them are most likely candidates).
