I just don't put much weight into the TDs considering Tiki has one of the best shortdistance runners in the game as his backup, while Westbrook gets to stay in for the TDs.
Westbrook is obviously a great player, a gamebreaker and one of the best in the league. Tiki is also one of the best. It's too bad 4 RBs couldn't make the team. Reminds me of the year LT didn't make it.
Fairly decent read:

Westbrook has 6 carries and 2 catches from inside the opponents 5 yard line this season and he's scored 3 TDs on those plays.Tiki has 4 carries and 0 catches from inside the opponents 5 yard line with 0 TDs.
Take away the "goalline" work for both players and Westbrook still has 8 TDs to Tiki's 1 (in 1 fewer game).
BTW, I agree that all 4 RBs in the NFC had Pro Bowl type seasons, but Tiki's lack of TDs would have been the easiest reason to exclude him. Westbrook has been amazing and deserved to go. In general, I think people with great non traditional stats tend to get unfairly excluded in Pro Bowl selections (i.e., Westbrook's receiving, Vick's rushing, CBs or DL with high tackle numbers).
