As PFT suggests, Aromashodu had a dissapointing 2010 seaon when expectations were high on him to perform. However, considering that he has aready been on the Colts and knows the system, it wouldn't be a real hard transition for him.
After Devin left the Colts following the 2007 season, he did not see game action until the 2009 season. However, he showed several flashes during this time, most notably in the classic Chicago-Minnesota Monday nighter in which Aromashodu caught the walk-off touchdown pass in overtime beating Pro Bowler Antoine Winfield.
Aromashodu has shown that he has the talent to play with anyone, he just has yet to put it all together. After leaving the Colts he definitely seemed as if he improved by leaps and bounds. If the Colts can sign him, it would be a good pick up that in the worst case would add depth to the WR core and in the best case would add a great playmaker to an already loaded offense.
