I think Tiki is going to have a strong year. I'd draft him as my second back.
If Manning starts, he'll be looking to dump it off under pressure.
If Warner starts, he's used to dumping it off to his backs.
An article on Giants.com, stated that Coughlin had Tiki Barber running more aggressively and carrying the ball differently.
I think he'll not only get the yards rushing and receiving, but find the endzone more often as well.
Just my opinion but I think Tiki will be good for an average of
12 - 14 pts. a game.
