If there was NCAA Conference All-Star teams for the NFL. Who wins?

Strictly hypothetical to be considered for no reason other than discussion.

If there was an allstar system where teams were created based on the conference they played in the NCAA. Who would have the strongest team?

SEC Team

Offense:
QB: Peyton Manning, Matt Stafford & Cam Newton
RB: Arian Foster, Eddie Lacy, Mark Ingram, Stevan Ridfley
WR: AJ Green, Julio Jones, Alshon Jeffery, Rueben Randle
TE: Jason Witten

Defense:
OLB: Aldon Smith, Justin Houston, & Courtney Upshaw
ILB: Patrick Willis, CJ Moseley, & Jarvis Jones
CB: Patrick Peterson, Joe Haden, Morris Claiborne, Dee Milliner
S: Eric Berry, Eric Reid, Tyrann Mathieu

Special Teams:
K: Blair Walsh
P: Brad Wing

I'm sure I am missing loads of notable players but this was who I could think of off the top of my head.

What would the other conferences look like? Is SEC the strongest?
