After a fairly quiet week four, the college wrestling landscape erupted with a flurry of activity. Most of it emanated from the desert oasis we all know and love, Las Vegas. We had the proverbial calm before the Cliff Keen Las Vegas Invitational brought a literal apocalyptic storm to the rankings. 

More than 100 ranked wrestlers made it on the brackets at the CKLV, and as expected at a tournament this early in the season, chalk did not often prevail. To help you try to make sense of the rankings volatility, we've highlighted the biggest movers up and down the rankings in our weekly stock report. 

The latest and greatest NCAA rankings with explanations can be found here. 

Stock Going Up - Austin DeSanto, Drexel, 133 Pounds

DeSanto got pushed out of the top 20 last week but wouldn't be denied this time, especially not after teching No. 2-ranked Stevan Micic, last year’s fourth-place finisher at the NCAA Championships. DeSanto still remains vulnerable on bottom, but his relentless attacks from neutral — almost always set up with a vice-like tricep grip — helped make him the biggest gainer of the week, going from outside the top 20 to No. 6.

Stock Going Down - Brandon Womack, Cornell, 174 Pounds

All-American Brandon Womack didn’t place at the CKLV, showing the insane depth of this year’s edition of the annual tournament. Womack’s losses to CJ Brucki and Cal Baptist’s Nolan Kistler, coupled with so many other strong performances in his weight class, send his stock plummeting and his ranking down from No. 8 to No. 17.

Stock Going Up - Taylor Venz, Nebraska, 184 Pounds

One guaranteed way to raise your stock value is to beat four top 10 opponents in one weekend. Nebraska’s redshirt freshman phenom (the Huskers have a couple of those) did just that and is the second biggest gainer of the week, moving up 13 spots from 19 to six.

Stock Going Down - Ryan Millhof, Arizona State, 125 Pounds

Arizona State’s All-American 125-pounder was involved in a couple controversial matches at the CKLV. According to the officials, however, Millhof was defeated by Jay Schwarm and Drew Mattin and drops seven places to No. 13.

Stock Going Up - Drew Mattin, Michigan, 125 Pounds 

Wolverines true frosh Drew Mattin beat two All-Americans and a surging Christian Moody to raise his stock nine places from 20th to 11th. Mattin's only losses at the CKLV were to the eventual champ, Taylor LaMont, and to NCAA finalist Ethan Lizak. Mattin also finished ahead of Jay Schwarm at the tournament, leaping ahead of him in the rankings and becoming the biggest gainer of the week in his weight class.

Stock Going Down - Kevin Beazley, Michigan, 197 Pounds

Michigan appeared to fill an important hole in its lineup when the Wolverines pulled in All-American Kevin Beazley as a graduate transfer from Old Dominion. Beazley struggled a bit at the CLKV, however, lowering his stock from No. 5 to No. 13 after taking losses to Jacob Seely and Tom Lane, finishing outside the top eight. 

Stock Going Up - Nick Zanetta, Pittsburgh, 141 Pounds 

Pitt senior Nick Zanetta has been on the periphery of an NCAA tournament invite for several years. He went a long way to securing his first bid at the CKLV by beating three qualifiers and highly regarded Iowa State freshman Kanen Storr. Zanetta's stock soars as he goes from being unranked to No. 12.

Stock Going Down - Ryan Solomon, Pittsburgh, 285 Pounds

Three-time NCAA-qualifying heavyweight Ryan Solomon was having another quality season but ran into some turbulence at the CKLV. The Pitt senior's stock falls as he drops seven spots from eighth to 15th after losing to Shawn Streck and Nathan Butler. 

BUY OR SELL, YOU MAKE THE CALL: Josh Terao, American, No. 9 At 133

American University's 133-pounder had a fantastic CKLV tournament, making the finals before being stopped by Luke Pletcher. Terao rose from 13th to ninth in the rankings, but many feel that is still too low, especially with Jack Mueller sitting at No. 5, a wrestler Terao beat soundly 6-0 in the CKLV semifinals. Terao's early-season loss to Dennis Gustafson, who was also at the CKLV but did not place, is holding Terao back from rising further. But is he being penalized too much? 

The 133 weight class has been all over the map. Austin DeSanto lost to Ian Parker, who lost to Josh Terao, who lost to Dennis Gustafson, who lost to Korbin Myers, who lost to Stevan Micic, who was obliterated by DeSanto. But if you think you have it figured out and believe Terao is too low, now would be a good time to buy all the Josh Terao stock you can get your hands on.
