As talented as these players are, they are still tight ends, and will need to continue to be targeted often as receivers instead of simply blocking to have a chance at the Rookie of the Year award. But Hernandez and Moeaki have shown in two weeks that they have the confidence of their offenses to challenge the running backs and wide receivers on this list.

1. Lions RB Jahvid Best (first round, 30th overall)
Last week's ranking: 3

Best became the first rookie in NFL history with at least 75 rushing yards, 150 receiving yards and three touchdowns in one game with his giant Week Two output against the Eagles. He finished with 17 carries for 78 yards and two TDs and caught nine balls for 154 yards and a TD receiving. After being used sparingly in Week One, the Lions fed Best a ton on Sunday, and he showed the league what he is capable of. He is the clear-cut Rookie of the Year favorite through two games.

2. Lions DT Ndamukong Suh (1, 2)
Last week's ranking: NR

Suh had a monster game against the Eagles with eight tackles, a sack, and two tackles for loss. Keep this in mind: Suh is a defensive tackle, not a linebacker, yet he's racking up tackles and sacks. And, if you forgot, Lions head coach Jim Schwartz will remind you of how impressive it is. "For defensive tackles, it's hard to get sacks, and he's got one in each of his first two games. That's tough billing to live up to," Schwartz said.

3. Rams QB Sam Bradford (1, 1)
Last week's ranking: 2
