SJAX or WESTBROOK?

10 team league Ive got the 3rd pick in my fantasy football draft and i figure LT and Peterson will go 1-2 as ive seen in most mocks this year this is a league ive been doing with friends and family for three years as a redraft league but this year is gonna be the 1st year we will keep 3 players into next year thus making SJAX age very enticing so what do you guys think anyone else i should consider and any other tips
