Detroit Lions coach Jim Caldwell was unequivocal about his interest in free-agent quarterback Colin Kaepernick. “No,” he said, “we have the guys that we want at this point in time.” Those comments came moments before the Lions opened organized team activities practice to reporters for the first time this season. On the field, there was Matthew Stafford, a 5,000-yard throwing, one-time Pro Bowl, two-time playoff participant. Behind Stafford are two sixth-round draft pick investments: former Michigan Wolverine Jake Rudock is No. 2 and former Miami Hurricane Brad Kaaya is No. 3. The Lions have an entrenched starter and two developmental prospects, which leaves little room or need for the Lions to take on a reconstruction project like Kaepernick, the highly scrutinized former San Francisco 49ers quarterback. “It doesn’t have anything to do with whether or not he’s capable, just in terms of what we were doing,” Caldwell said. “We have Matthew. We have Jake and, obviously, we drafted a young man in Brad.” Caldwell stressed it wasn’t about Kaepernick’s ability. After all, Caldwell saw that ability up close and personal when he was the offensive coordinator for the Baltimore Ravens in their Super Bowl XLVII win over Kaepernick’s 49ers.
