"We talk about it all the time", said Spartans head coach Robert Jones. "We're trying to create our own history.
"We knew Morgan State wouldn't go away", he added. "Coach (Kevin) Broadus is a good friend of mine, and we said all year that we were the two best teams in the league. We showed it tonight.
"It was a dogfight the whole time. We watched their first two games, and they were down by nine at the half, so we just said this wasn't going to be the third game in a row."
Broadus said after the defeat "they were the better team. They played a helluva game and they were the better team today. We had our chances to make a run and we just couldn't get over the hump."
