There is not a better single event in the entire year to evaluate than The Opening, held annually in July on the Nike campus. With more than 160 of the best prospects in the country all in one place, it gives us a chance to see three days of competition from the skill players, five days of competition from the quarterbacks and padded, physical work from the offensive and defensive linemen.

Kahlil McKenzie will be pushing Josh Sweat all year for the No. 1 ranking.

LINK: Updated Top247

Following the week out in Oregon, we have made a slew of changes to the Top247 for the class of 2015. Likely this is the most movement you will see in a single update until the All-American circuit in January. Below we take a look at the biggest movers.

A new No. 1

Josh Sweat takes over the title as the top player in the nation after gradually ascending the ranks throughout the spring and summer. The 6-5, 240-pound defensive end out of Chesapeake (Va.) Oscar Smith, barely earned the nod over new Tennessee commit Kahlil McKenzie who came in at No. 2.

McKenzie had a dominating week at The Opening and following that effort, he’ll be in play as a No. 1 candidate throughout the year because of his college ready body, his power and his competitive mentality. We gave the nod to Sweat due to his immense upside.

Sweat is still on the early end of his ascent as a player but the production is already there with 22 sacks as a junior. Athletically he can proudly carry the ‘freak’ title after testing as one of the top ten athletes in the country regardless of position in the SPARQ Combine national championships. He displayed that athleticism all week in Oregon and his best off the edge was the best we saw. Maybe most impressive, Sweat was dealing with a hip flexor injury all week and we never saw him complain or make excuses, he just kept his head down and competed. With size, athletic upside, production and toughness, we love the skill set that Sweat brings to the table.

A new top arm

Heading into the opening, Ricky Town was the No. 1 player overall and the top quarterback in the country. Josh Rosen was No. 2 in both. Following The Opening, there is a third name that has jumped them both and it’s Stephenville (Texas) High School’s Jarrett Stidham.

Jarrett Stidham impressed in every facet during The Opening. Baylor and Oregon are still giving chase.

The Texas Tech commit checks in at No. 16 overall in the country, earning the top overall quarterback ranking. All week long at The Opening and the Elite 11, Stidham was composed and collected. He showed outstanding accuracy, a quick release and he spun the ball consistently. He also gave us the big throws.

All of that is important and valuable but there is more to his No. 1 overall ranking. Given the circumstances of the Elite 11, with the quarterbacks being asked to learn a new playbook, prepare for the week, compete in everything they do, we find tremendous value in the event. But we also went back and re-watched Stidham’s film. When you put the week he had in Oregon in context with him being a first-year starter as a junior, throwing for 30 touchdowns and rushing for 800 yards, being an 800-yard receiver as a sophomore, all of that lends to a kid that will develop rapidly and find a way to be successful.

The five-star shakeup

In addition to Stidham’s arrival in the five-star ranks, five other five-stars joined the fraternity, while six names dropped to the four-star ranks.

The highest five-star debut was Byron Cowart who checked in at No. 15 overall after a complete and dominating week at The Opening.

Clemson commit Deon Cain completed his ascent into the five-star ranks after following up an outstanding spring with another fantastic performance at The Opening. As a high school quarterback who is still learning the wide receiver position, he’s got a huge ceiling and he is now the No. 1 wide receiver in the country.

Alabama commit Blake Barnett is another prospect that has consistently impressed this spring and he earned the Elite 11 MVP award in Oregon. With size and arm strength, Barnett may be the biggest sure thing at the quarterback position in 2015.

Barnett’s favorite target during the week also joins him the five-star ranks as Calvin Ridley was probably the single most dominant skill player at The Opening. Ridley checks in at No. 22 overall after a highlight filled camp.

Calvin Ridley led the week in highlight reel worthy plays.

Porter Gustin is the final new addition to the five-star ranks, coming in at No. 23 overall. The freakish 6-5, 240-pound linebacker is one of the nation’s top athletes. On the next level, he could be a linebacker, a rush end, a tight end, even a quarterback and he was one of the most athletic in attendance in Oregon.

After a injury-filled offseason and with limited opportunity to verify what we’ve seen on film, Canton Kaumatule dropped just outside of the five-star ranks to No. 33 but has a great shot at moving back in with new film or clean bill of health. Shameik Blackshear and Jacob Daniel also fell right outside the five-star realm as the bar continues to rise.

While we still love Daron Payne’s upside, he dropped back to No. 53 nationally following The Opening. Futher review of Jalin Barnett moved him from the five-star range down to No. 63 overall. Meanwhile Jashon Cornell has been re-slotted to No. 67 nationally after we had a chance to see him in two Nike camps and The Opening.

Notable big movers

Louisiana athlete Donte Jackson impressed at The Opening due to his speed and versatility. He moved up from No. 87 to No. 51 overall.

South Carolina commit Mark Fields is a name to watch heading into the season. His speed and big play ability land him at No. 58 up from his previous ranking of No. 82.

Gilmer (Texas) High School cornerback Kris Boyd saw his stock soar at The Opening due to his speed and length at the cornerback position. He’s up from No. 154 to No. 64 nationally.

Arizona commit Keenan Walker displayed added strength and physicality this week and moved up from No. 133 to No. 78.

Penn State commit Brandon Wimbush had the strongest arm we saw all week and he moved up from No. 178 to No. 80 overall.

Hands down, in this setting, Roquan Smith was the best linebacker in attendance at The Opening. He’s up to No. 83 in the nation.

Missouri commit Drew Lock earned an Army All-American Bowl invitation with his performance at the Elite 11. He also earned a bump to inside the top100.

Utah native Osa Masina had another solid effort as an athletic space linebacker getting a bump up from outside the top 150 to just inside the top 100.

There were several prospects that were previously outside the Top247 that found their way in after proving themselves in Oregon. Center Tommy Hatton was outstanding all week and checks in at No. 237… Notre Dame commit C.J. Sanders is everything you want out of a slot receiver and moves up to No. 226…Texas A&M commit Justin Dunning was phenomenal during the week in Oregon. His length and range were unmatched. He checks in at No. 208 but if he shows increased physicality in the run game this fall, he’ll rise even higher…Quarterback Sam Darnold continues his steady attack on the rankings, this time jumping up to No. 204 nationally after a strong week…New Vanderbilt commit Josh Smith showed off outstanding length and athleticism and in Oregon and checks in at No. 192…Justin Reid is underrecruited but is no longer under-ranked by 247Sports. The Louisiana native is now ranked No. 165 nationally…Lawrence Cager showed off his size and athleticism at The Opening and earned a boost up to No. 152
