Previewing USC's official visit weekend

At least eight official visitors will be on the USC campus this weekend, as the USC coaches look to put the final touches on another outstanding recruiting class.

Just like last weekend, it all starts on the offensive line with this group.

Kyle Murphy (San Clemente, Calif./San Clemente) is the headliner, and one of the most important uncommitted recruits left on the board. He's thought to be a lean to Stanford and just had a very successful visit there last weekend, but he'll continue to give USC a look and said he will likely make a decision in the week following his official visit to USC.

Offensive linemen joining Murphy this weekend are Zach Banner (Lakewood, Wash./Lakes) and Hiva Lutui (Euless, Tes./Trinity). Banner has narrowed his choices to a final three -- Oklahoma, USC, Washington -- and while many think he is a USC lean, the Washington staff has done a good job recruiting him of late. This is his final visit, and Banner said he will take all the way to signing day to make a decision. Lutui's situation became far more interesting early this week. After an official visit to UCLA last weekend, Lutui decommitted from the Bruins and said he was looking at a final three of USC, Utah and BYU. It looks at though the USC coaches would like to take an additional tackle and guard prospect in this class, and Lutui would nicely fill the latter spot.

Along the defensive line, a couple of big bodies will be on campus. Aziz Shittu (Atwater, Calif./Buhach Colony) and Leonard Williams (Daytona Beach, Calif./Mainland) would be terrific gets for a class lacking a big bodied defensive lineman. Shittu was an early commit to Stanford and may have been leaning to California before the departure of Tosh Lupoi. Now, things could come down to Stanford and USC.

Williams was born in Los Angeles before moving to Florida, and his top three schools are Auburn, Florida and Florida State. He recently mentioned that it may not have been the best idea to take all of his official visits, because each one adds to the confusion of the process. Williams has the ability to play all four positions along the defensive line, but said every school is recruiting him as a defensive end.

Three USC commits will also be in attendance on official visits. Fullback Jahleel Pinner (Mission Viejo, Calif./Mission Viejo) is solid to USC and will be giving his best recruiting pitch. Tight end Jalen Cope-Fitzpatrick (Rocklin, Calif./Whitney) and defensive end Pio Vatuvei (Patterson, Calif./Patterson) have taken other official visits, but have USC alone at the top of their lists. A good visit this weekend could lock both players into becoming Trojans.

One late scratch from this weekend is defensive end Tyriq McCord (Tampa, Fla./Jefferson). McCord was scheduled to attend, but said his mother became sick late this week and he will postpone his visit to the following weekend.

As with last weekend -- and all official visit weekends for USC -- there will be little surprise to hear additional names thrown into the visit list Friday night and into the weekend.
