One thing I think is safe to say is that Cruz is not a one year wonder... not only had he been displaying his kind of talent prior to injuring himself during his rookie year, but the way he managed to make adjustments and improve himself during last season shows that he knows what he has to do, regardless of what defenses do to adjust. His physical talents and concentration on bringing in cacthes, his uncanny ability to control and adjust his body to pull in catches and make smart moves with the ball afterwards over and over again, proves to me that he can do exactly what he wants to do when out there on the field.
I think the offense will make their own adjustments so his productivity may not exactly match what he did last season, for numerous other reason, in example... hopefully a much improved running game, which will take some of the pressure off him and Eli. To me, it seems those two guys bailed the offense out on 3rd down so many times it might have been a little too close for comfort. None the less, they have proved that they can get it done when needed.
All in all... I look for Cruz to keep improving and making a name for himself. Hopefully he will stay healthy and by mid season, the Giants offer him a contract that reflects his value to the team's future.
