BREAKING: Grant Mullins has committed to Cal as his transfer destination per his Instagram https://t.co/203han7GQ1

Shortly after wrapping up a visit to Michigan, Columbia grad transfer Grant Mullins announced his commitment to Cal for his senior season. The combo guard was also considering Syracuse.

This leaves Michigan with an open scholarship for next season, and unless another grad transfer candidate emerges out of the blue, it's likely John Beilein will use it on a late-rising 2016 prospect—or, like he did last year, leave the scholarship open, which seems like the least-desirable route.

Sam Webb reported last week that Michigan was showing interest in four-star WI F Kostas Antetokuonmpo, but there hasn't been any word on him since then. The coaches checked in on IMG Academy three-star F Aleem Ford last week; he committed to Wisconsin shortly thereafter. Unless the coaches can get Antetokuonmpo to campus, they might be scrambling for other options.

Those other options almost certainly won't include Spike Albrecht, who's already visited Purdue and plans to see Wichita State and Syracuse. Even if Michigan decides they're willing to sacrifice some early development for Xavier Simpson to bring Albrecht back, the Wolverines won't represent Spike's best opportunity to play the most minutes.
