Smith made the right choice when he chose to sign with the 49ers as he moves from one quarterback with a big arm, Joe Flacco, to another quarterback with a big arm, Colin Kaepernick. Earlier in the offseason, Kaepernick spent 10 weeks working on his mechanics and the reports have been glowing. This is great news for Smith who should be able to use his great speed to get deep, while defenses need to respect Kaepernick's ability to run. Aside from his 11 TD receptions, Smith's numbers were very pedestrian in 2013 providing a great buy-low situation with plenty of upside.
