"This trade gives us a chance to improve in key areas moving forward," said General Manager Ryan Grigson. "David is a very competitive football player and we welcome his style of play and energy. At the same time, we wish Delone well with his opportunity to play for another first-class organization and we thank him for his efforts."
Reed was a 5th round pick of the Ravens in 2010, and has just 5 career receptions. However, it seems this move was made for Reed's special teams ability. Colts.com is touting Reed's 39 kickoff returns for 1,150 yards.
The move was also likely made due to injuries and inconsistent play at the receiver position all throughout training camp and thus far in preseason for the Colts. Second-year wideout Griff Whalen is dealing with a groin injury while rookies Lanear Sampson and Jeremy Kelley have done nothing to warrant a roster spot.
Regarding Delone Carter, he was as good as gone from the moment the Colts signed Ahmad Bradshaw as a free agent. With Baltimore he gets new chance to prove he can play at the NFL level.
