Well, this was fast. Per his Twitter account, Vanderbilt freshman QB Jamil Muhammad — who enrolled in January and participated in spring drills — has entered the transfer portal.
So, technically, Muhammad could opt to return to Vanderbilt (and we’ll note that he’s still listed on the official roster as of this writing), but there are two things of interest: one, that tweet is geotagged in Alabama, indicating that Muhammad isn’t currently on campus; and two, he’s leaving prior to his freshman year even starting.
Without any further comment, it’s hard to speculate on the why here. Muhammad wasn’t likely to play in 2019, but perhaps he’s looking at the competition, both currently on the roster and incoming (2020 QB commit Ken Seals) and not liking what he sees. Or perhaps this is something else. We probably won’t know until he announces a transfer destination. One thing this probably can’t be is a desire to be closer to home: there basically aren’t any FBS schools closer to his home in Madison, Alabama.
Again, this doesn’t really affect Vanderbilt much for the current season, but it seems to be a pretty curious move.
