''I have all the confidence I can have,'' he said. ''It's healed now, so I don't have any excuses.''
Mosley started every game and made the Pro Bowl as a rookie last year. He had 129 tackles, three sacks, two interceptions and a forced fumble, numbers that look even better considering he played the final six games with the broken wrist. He underwent surgery in the offseason and was cleared for training camp.
The Ravens picked the 6-foot-2, 235-pound inside linebacker from Alabama in the first round of the 2014 draft, and after the impressive rookie season he just wants to keep getting better.
''You can never take a step back,'' Mosley said. ''So it's just building from everything I did last year and going up from there. The bar was already set at the position when I got drafted, and I did what I did last year. So for me, I've got to make sure I'm doing the right things and keeping my body right as usual.''
Coach John Harbaugh said he's confident that Mosley will keep getting better and not only again help the Baltimore defense but grow as a player.
''I know sometimes guys who have (a) great Year 1 don't have (a) great Year 2 - don't follow it up - but that should never be the case,'' Harbaugh said. ''If your head is screwed on the right way, you should have a better Year 2, and I believe C.J.'s head is screwed on the right way.''
Mosley impressed many teammates with his attitude and how hard he worked last year.
Guard Kelechi Osemele said that Mosley never acted like a rookie and expects the linebacker will improve plenty in his second season.
''He works on his technique; he's a student of the game,'' Osemele said. ''He has tremendous confidence, and he's very talented.''
