McDonald has a monster frame at 6-foot-4, 267 pounds, and was used primarily as a slot receiver for the Rice University Owls. He also has incredibly long arms and gigantic hands that will help him in becoming a better blocking tight end.
Also with the long arms, McDonald catches the ball away from his body, thus making him appear bigger than his frame dictates, which could be a real asset to 49ers head coach Jim Harbaugh in the passing attack.
In his four years at Rice, McDonald had 119 catches for 1,504 yards and 15 touchdowns. Additionally, he ran the ball a total of seven times for 52 yards, and also finished out his career as the team’s long snapper — not too bad for a man without a true set position.
McDonald is seen as upgrade over Delanie Walker, who left and joined the Tennessee Titans in free agency earlier this off-season. While he isn’t polished, McDonald doesn’t have to step right into the spotlight as the 49ers do have arguably one of the best tight ends in football with Vernon Davis.
While most don’t think he will unseat Davis anytime, he could be an excellent compliment and might get a lot of looks from Colin Kaepernick due to the attention being focused on Vernon.
