Since October, Mel Kiper has not wavered on his top two picks for April’s draft. In his newly released mock draft, he still has defensive tackles Ndamukong Suh as No. 1 and Gerald McCoy as No. 2. He said they’ve both been steady and solid since the fall. The Lions have the second overall pick. St. Louis is first. Kiper loves both Suh and McCoy. He thinks either would be a good fit for the Lions and/or Rams. “They both gave you one thing — consistent productivity,’’ Kiper said during a conference call on Wednesday. Kiper, the NFL draft guru, said that McCoy would give a team more versatility since he can play the 3-4. He’s a little more sudden and explosive. But he’s had Suh at the top spot for a reason. He sees him as a tackle who is strong, powerful and an outstanding bull rusher. “He’s a warrior,’’ Kiper said. It’s expected the Rams will pick one of them, although they could also opt for a much-needed quarterback. It seems like no matter what St. Louis does, this will be a win-win situation for the Lions.
