2nd pick in 10 team standard

2nd pick in my 10 team standard league.
Assuming Barkley is #1 who should I get?

my ranking would be barkley, mccaffrey, Kamara, zeke out of those 4

It’s just so difficult caus cmc is solid but better in ppr
Kamara is good but has Latavius Murray right behind him
Then zeke is top 2 rb is he plays whole season but don’t know when the contract stuff will get settled
