Updated: Celtics likely summer league roster, including 'one of most in-demand undrafted free agents'

Here's what we know about the Celtics summer league roster so far, which will begin play in Utah on July 6:

DraftExpress slotted Holmes at No. 33 in their final mock draft, and has him at No. 23 on their list of top 100 prospects.

Babb is the more well-known name of the two, but both he and Johnson spent the bulk of 2014-15 with the Maine Red Claws.

The Celtics second-round pick from 2013 was in Spain last year.

A 6'6" small forward out of Baylor, O'Neale is No. 100 on DraftExpress' prospect list.

All four of the C's draft picks, Terry Rozier, R.J. Hunter, Jordan Mickey and Marcus Thornton are expected to suite up as well.  Brad Stevens also suggested that Marcus Smart will join the squad in Utah and Las Vegas:

In addition, King writes James Young is a likely participant, and says Danny Ainge has mentioned Phil Pressey is a possibility.

Hunter's at Georgia State, Corey Walden from Eastern Kentucky and Holy Cross' own Malcolm Miller, who you may have seen dunking on YouTube.  Murphy says the roster is currently at 12 players and doesn't mention O'Neale, but states that the team plans to bring 13 to Utah and Vegas.  The Celtics used 11 players in Orlando last summer.
