It's interesting that college bar is still relatively difficult skills (Paks, Shaposh, Toe-on Tkachev, E- dismounts) while Beam, Floor, and Vault are relatively waterdowned in comparison to elite/high level JO. For Vault, we are seeing fulls instead of 1 1/2 or doubles. Beam- no triple flights sequences. Floor- first pass is usually a double pike..
*bars:I'd say that the reasoning for that is on bars it's pretty straight forward, you catch your release or you don't, and you can pretty much nail a dismount...so in terms of deductions, if you're a reliable bar worker, the risk is less to keep your big skills in college....
*Vault: 9.95 for a full with a good chance to stick your landing; 1 1/2: 10.0, blind landing, and with steps, likely to be more deductions than the delta in the SV....
*same with beam, unless you nail (and I mean no wobble, bend at the waist, lift your leg, windmilling your arms etc) the triple series 110% of the time, not worth the .5 deduction when you're on the ground after falling...the "bonus" of doing it isn't worth the risk of the fall/deductions , if it's not perfect.
*Floor...not a ton of regular JO kids have E passes like full ins or Arabians so not surprised that you don't see more in NCAA... they get to college at at least 18 yrs old so teaching those type of skills, while not unheard of, is more difficult to begin with...and again, the risk of not doing something clean isn't worth it in NCAA.
It all boils down to NCAA's big focus is clean and stuck and up to code...kind of like the "keep it simple stupid" philosophy for scoring well...and Oklahoma is a perfect example ..they are incredibly clean but I don't think they have many 10 SV vaults but they make up the difference in being clean on all 4 events and not giving away tenths in sloppiness.
