Although I'm a fan and not a scout, it's hard for me to see why she wouldn't be able to score the same way she did at Fairfield.
Lou will be able to score at the same level she did at Fairfield for two reasons.
1) UCONN is a much more equal opportunity read and react offense that does not overly feature a go to player as Fairfield did with Lou. You can easily verify this by looking at a UCONN past season box score which shows a fairly equal distribution of FG attempts between players 2-6. Nika is somewhat of anomaly here. By contrast a Fairfield season box score will show you that Lou led the team in FGA by a margin of almost 2X- meaning she took almost twice as many shots as the next highest player on the team.
Lou is not going to be getting nearly as many FGA attempts as she did at Fairfield and quite candidly I would not be surprised even if she earns a starting stop for her to be the 4th offensive option for UCONN.
2) On a nightly basis Lou will likely be facing a much better defender that she was facing while at Fairfield. The Big East by itself is a significant step up in the caliber of player over Fairfield and the MAA. UCONN's out of conference schedule is exponential step above BE play. In the UCONN OOC schedule you can expect Lou to be matched up against some pretty awesome defenders:
Duke will feature a trio of Baluguun, Cyleste Taylor, Ashlon Jackson. NC St defense will feature Saniya Rivers and Jakia Brown-Turner.
Notre Dame will feature Sonia Cintron and KK Bransford. Maryland will feature about 6 quality players that are of similar size to Lou but the MD defense will be anchored by Diamond Miller, Briane Alexander and Abby Meyers. TN will feature Jordan Horston-who can be motivated to be a quality defender-allegedly. Lastly SC will rely on Brea Beal who is 3 and 1 in her 4 starts against UCONN and at times was the best defensive player on either team in those 4 matchups. Put any of the players that are named in this paragraph into the MAA and they are likely the defensive player of the year.
Lou has a great set of tools most importantly an accurate stroke and fluid movement but to expect her to score at the same clip she did at Fairfield is just not realistic. Thank God Lou is here though.
