Giants.com has a good wrap-up on the TE position for the New York Giants as we go into the draft and the 2008 season. Some have speculated that because Boss is not nearly as adequate a blocker as Shockey, that Boss was used in routes more than Shockey so that his blocking would be less exposed. What this implies is that Shockey ironically ended up being a victim of his own success; he was held in to block more often because he was doing it so well.
For 2008, what would be a good development is having Boss become proficient at blocking so that the Giants could be more flexible in sending out either TE for a pass or keeping either in for pass protection. One thing is for sure- the Giants are in an enviable position at TE.
