No. 1 -- What's LB Skov's status? LB Shayne Skov's rehab from a knee injury is on schedule and he is expected to be ready for fall camp. However, the fallout from a Jan. 29 arrest for allegedly driving under the influence is unclear. Coach David Shaw would not divulge the details of Skov's punishment, but he said it was handled internally. No. 2 -- What leaders will emerge? Offensively, RB Stepfan Taylor, C Sam Schwartzstein and TEs Zach Ertz and Levine Toilolo have already taken bigger roles as vocal leaders, Shaw said. That's a good sign because replacing what QB Andrew Luck was able to do from a leadership standpoint is not a one-person job. No. 3 -- WR depth? Ty Montgomery is the only returning WR who had more than eight catches last season and could miss the entire spring with a hand injury. Candidates to work their way into the WR rotation include Drew Terrell, Jamal-Rashad Patterson, Jemari Roberts and Jordan Pratt.
