And he will make the trips armed with something he has not had since committing to the Terps in July 2008.
"I was a non-qualifier out of high school, but recently got the (needed) score on the ACT,'' said Mackall, who attended Edmondson-Westside High in Baltimore. "I found out about four or five days ago. (Fork Union) was definitely worth it. At the beginning, I was kind of mad, but now I'm happy about it.''
Mackall considers himself "still committed to Maryland,'' but he does want to see what other opportunities may exist.
"I don't have any favorites. I'm just looking,'' Mackall said. "I have no other visits set up, but I plan on looking at Michigan, too. I'm not looking at too many schools because of time frame. I'm trying to be in school in January.''
Mackall said Purdue and Michigan sent him written offers, and he added Rutgers is talking about offering him.
And he does have knowledge of the Scarlet Knights' program.
"They started calling recently, and I know one of the coaches was calling me last year when I was in high school,'' Mackall said. "They were a team that I liked. I watched them play a lot. They looked pretty good to me, so I said, ‘Why not look at them?' ‘'
But any school trying to land Mackall, one necessary trait must exist on defense. Mackall wants to be used as a hybrid player, splitting time as a rush-end and also dropping into coverage, sort of in the way Rutgers uses current senior George Johnson.
"I'm not looking at any schools that do not have a hybrid position,'' Mackall said. "I'm looking for a place where I can be comfortable, and we can win at the same time. As long as I'm comfortable, I don't mind going somewhere where there is a lot of competition. That's what I want.''
