The Lions signed two veteran offensive linemen the past two days with plenty of starting experience, but coach Jim Schwartz insists that doesn’t mean they’re unhappy with rookie third-round pick Larry Warford or anyone else. “It’s absolutely not an indictment on anybody,” Schwartz said. “It’s just a fact of being able to add quality players and keep adding them. We have 90 guys in camp, so might as well take advantage of that and set ourselves up the best we can.” Jake Scott, who has played for the Eagles, Titans and Colts and started most of his nine NFL seasons at right guard, signed a one-year contract Tuesday with the Lions. On Monday, the team inked former Titans guard/center Leroy Harris. The Lions cut starting right guard Stephen Peterman earlier this off-season, and when they missed out on adding a tackle in the draft — a move that would have shifted last year’s first-round pick Riley Reiff to right guard — they took Warford with intentions of making him a starter. Warford worked at second-team right guard during Tuesday’s OTA practice, as he has most of the off-season. Schwartz said it’s too early to call Warford a starter, but left guard Rob Sims said the rookie has impressed him in the month or so they’ve been together. “Larry’s going to be a good player, he’s just got to learn the game,” Sims said. “That’s the hardest thing about learning the technique here, it’s hard to just come right out of the gate and just know everything. He’s listening, and he’s learning, and he’s going to be a good player down the line.”
