He doesn't play like Kam, he's just big.
I think during the draft I saw Kyle Duggar as well.I forget who it was but one of the analysts on the draft shows compared him to Jeremy Chin. Don't know if that is accurate or not though.
The skillset and talent are undeniable, and he certainly has the potential to be a complete safety. He's just not Kam-lite in current form. They could try to mold him into that, but he doesn't really have the instincts and mentality Kam did entering the league.
