I'd be willing to bet that Danbor was referring to game experience as opposed to physical age..... Unless my memory is failing me, we returned 7 or our top 8 scorers, and I believe we are in the top half of the B1G in minutes played, roster wise.... Maybe even top 4 or 5.
This is kind of an unusual team in that it is relatively young but also relatively experienced given their age. They're slightly younger than average, checking in at #214 per Pomeroy's experience category (basically, a weighted average of what class plays how many minutes). However, they're #13 in the country in continuity, which measures how many minutes are played this year by the guys who played last year.
We relied on freshmen more than any team in the league last year as they used 53% of our possessions. Maryland nominally had a few more freshman minutes but they were far less involved, at 44% of possessions. Every other team aside from Rutgers (38%) was under 30%.
Regardless, there's a difference between having one year of experience and three, and a difference in physical maturity. We're closer, but this is still kind of a young team.
