Caldwell caught 19 passes for 174 yards as a freshman. As a sophomore he looked like he was about to become a star when he finished with 43 catches for 689 yards and three touchdowns. He entered his junior year with huge expectations but a broken leg against Tennessee ended his season after just 10 catches for 148 yards. He was hurt early enough to receive a medical redshirt, and he came back in 2006 with a solid season. He had 57 receptions for 577 yards and six touchdowns on the year. Caldwell also ran track for the Gators in 2007, running the 100m. Caldwell had his best season as a senior, finishing the year with 52 catches for 721 yards and five touchdowns.
Caldwell is a player that has a lot of potential left in his game, despite playing quite a bit during his career. He is a good athlete, with solid size, and very good speed. He is not afraid to cross the middle and take a hit while trying to haul in the catch. He has the ability to get down the field vertically and can make plays with the ball in his hands. Caldwell even has experience returning kicks, with a career average of over 20 yards a return.
Caldwell has been productive, but that may just be because of the offense and his natural talent. He could still use some work on running routes. He needs to come in and out of his breaks quicker and sharper and become more consistent.
Caldwell has all the skills to become a solid receiver in the NFL. He has done everything he can in the post season to maximize his draft position. He had a good showing at the Senior Bowl, and followed that up with a fine showing at the combine. Caldwell could potentially hear his name called in the second round at some point.
