I'm well aware Eli had a very good season and was named 2nd team all-conference, had 15 rushing touchdowns, and had some monster games against Western Co, PSU, and Tennessee St. And after the season, he received offers from multiple FBS schools.
I'm also aware he had some games where his rushing production was low SDSU (10 rushes, 12 yards), MSU (10 Rushes, 35 Yards), UC Davis (8 Rushes, 21 yards), UNCU (12 rushes, 39 yards).
Both of these things can be (and are) true.
I think IAA was posing the question of what was the reason for those low production games against good(ish) defenses. It's not terribly dissimilar from playerrep's questions about Adam Jones.
Personally, I think Gillman is a great back. He's for sure a 1st team all-conference guy, likely a top-5 (possibly higher) for the Payton award, and has a good shot for first team All-American.
