Don't jump to any conclusions. Cholatse might be purposely "passing" on picks to see if he can get a player with a later pick.
Ex. If he wants to pick say a 2005 Jeter for his SS but would settle for 2002 Jeter if he couldn't get him, he could just keep passing on his 2002 choice until either the 2005 Jeter is chosen, or it becomes available to him (in which case he'd make his 2002 choice of whatever is available).
Nothing in the rules says you have to pick your choices in order and its a viable strategy to let picks drop by (if you really don't like any players in that year) as long as your willing to let other players pick ahead of you while you wait it out.
