"You're always looking for goals, and Thomas had 18 goals (last season)," Holland said. "Obviously, him getting bought out of his contract in Minnesota, we think we've got a motivated athlete."
The Red Wings were 23rd in the League with 209 goals, and their top three goal-scorers had 23 (rookie Dylan Larkin), 21 (Tomas Tatar) and 19 (Justin Abdelkader).
Ott, 33, is an abrasive fourth-line player. He had two assists in 21 games with the St. Louis Blues and had surgery on his hamstring in December.
Detroit re-signed goaltender Petr Mrazek, defensemen Danny DeKeyser and Alexey Marchenko, and forwards Glendening and Darren Helm.
Mrazek, who will go into the season as the No. 1 goaltender, signed a two-year contract worth $8 million (AAV: $4 million) on July 27, the day when his arbitration hearing was scheduled. He earned $737,500 last season, when he was spectacular in January (7-1-1, 1.32 GAA, .952 save percentage) but slumped from the middle of February until the end of the regular season, when he was pulled in five of 14 starts.
The 24-year-old lost the job to former No. 1 Jimmy Howard but returned to start Game 3 of the Eastern Conference First Round against the Tampa Bay Lightning and played the remainder of the series, which Detroit lost in five games.
Mrazek was 27-16-6 with a 2.33 goals-against average, .921 save percentage and four shutouts.
The previous day, DeKeyser signed a six-year contract worth $30 million (AAV: $5 million). The 26-year-old was the Red Wings' best and most consistent defenseman last season, and had eight goals and 20 points in 78 games. He was second on Detroit in ice time (21:48), behind Niklas Kronwall (22:00), and first among defensemen in average ice time while shorthanded (2:41).
Detroit signed Glendening to a four-year, $7.2 million contract extension on July 14 (AAV: $1.8 million), and retained Helm and Marchenko on July 1. Helm signed a five-year contract worth $19.25 million (AAV: $3.85 million) and Marchenko a two-year contract reportedly worth $2.9 million (AAV: $1.45 million).
The Red Wings also signed fourth line penalty-killing specialist Drew Miller. The left wing, who is coming off knee surgery, got a one-year contract reportedly worth $1.025 million, and right wing Teemu Pulkkinen, an unrestricted free agent, signed a one-year contract reportedly worth $812,500. Pulkkinen will miss the first two months of the season recovering from shoulder surgery.
