Player No. 4
Dean Lowry - DL
Dean Lowry was one of the bigger free-agent acquisitions for the Vikings this offseason. He was a starter for the Green Bay Packers, but also one who quietly just did his job, not being a liability in any way, but not being a standout either. Lowry just provides solid play, and that's probably the reason he's having a quiet training camp.
Lowry understands the defense he is in and his role in it. He does that role well, but he isn't someone who is going to sack the quarterback 10 times a season. He is an all-around defensive player who is stout against the run while providing the occasional pressure.
Minnesota's defensive line is one of the thinnest positions on the team this year. The three projected starters aren't elite by any means, and the depth behind them is questionable at best. If Lowry continues to do his role and can be solid against both the pass and run, they should be fine.
That being said, it would be reassuring to at least hear that he's making a play in the backfield or blowing by some blockers. Instead, mum has been the word, and if anyone forgot that the Vikings signed him, that's understandable.
