Only 10 members of the Rivals150 who are planning on attending college remain undecided. That number will be shrinking throughout the week as No. 2 overall Jalen Green headlines a group of ranked players ready to make their decisions.

Who is coming off the board and more in this week's Starting Five.

The top remaining prospect on the board in the class of 2020 and the No. 2 player overall in the senior class, Jalen Green will announce his college commitment on Friday.

The high-flying combo guard who is an effortless scorer is planning an announcement on Instagram live for 4 p.m. ET, where he is expected to choose between Auburn and Memphis with Fresno State hanging in there.

Now, regardless of which program lands his commitment, there will still be some sweating to do as Green could still choose to go overseas and play professionally. However, assuming he goes to school he would be a massive addition. Memphis is in need of a marquee player while Auburn -- who moved to No. 11 in the team rankings when they landed J.T. Thor on Sunday -- is looking to move their class comfortably into the top five.

Currently, my Futurecast pick is with Auburn but Memphis is very much in it and considered by many others to be the leader. I'm sure we are going to hear several rumors this week but the answer isn't far away.

As of late Sunday night, five-star senior shooting guard Joshua Christopher, who ranks No. 11 in the class of 2020, hadn't yet confirmed that he will be announcing his college decision. However, it's widely expected that he will announce a commitment before the end of the day Monday.

If he doesn't decide Monday, it won't be long after and the expectation is that he will be off the board sooner than later.

An explosive scorer with a college-ready body, Christopher is officially down to Arizona State, Michigan, Missouri, UCLA and USC. But, the reality here is that his decision is most likely to be either the Sun Devils or the Wolverines.

As it stands, my FutureCast is with Michigan and it has been my pick for a while now. Though anybody who has followed Christopher over the past few years knows that he can be a bit of a wildcard and there's little doubt he'll find an interesting way to announce his decision and nothing he does would be a surprise.

While Christopher may decide on Monday, four-star shooting guard Donovan Williams has set his commitment time for 7 p.m. ET.

Originally committed to Nebraska, Williams is now down to Kansas State and Oklahoma State.

A strong and tough two-guard, Williams returned from a torn ACL in just nine months to finish his senior season with several scoring outbursts.

Could Oklahoma State missing on J.T. Thor on Sunday have caused it to make a last-second pitch to swing things back in its favor? We'll see. But, as Williams prepares to decide, Kansas State has been considered a heavy favorite and it is my current pick.

One of the best shooters in the senior class, four-star shooting guard Kerwin Walton won't be deciding this week. However, his decision isn't too far off as he's set April 25 for his decision date.

Ranked No. 87 nationally in 2020, the 6-foot-5 product of Minnetonka (Minn.) Hopkins has excellent size and long arms to go along with his deadly jump shot.

With the announced transfer of junior big man Brandon Huffman made public at the end of last week, North Carolina now has the available scholarship needed to add Walton and I feel it is the team to beat so I've made my FutureCast in favor of the Heels.

Arizona and darkhorse Creighton are the two who are most likely in the thick of it with UNC while Georgetown, Minnesota and Vanderbilt are also in the mix.

It's not exactly a shrunken-down list, but five-star junior Moussa Cisse has at least cut things down a bit.

One of the most prolific rim protectors in the country and the No. 8 prospect in the class of 2021, the 6-foot-10 center at Memphis (Tenn.) Lausanne is down to a final 10 of Alabama, Florida State, Georgetown, Georgia, Illinois, Kentucky, LSU, Memphis, Tennessee and USC.

A move to the class of 2020 remains a possibility for Cisse and while I'm not ready to make a prediction on him, I do feel that Florida State, LSU and Memphis could be a bit ahead of the pack.
