ALLEN PARK — Coach Jim Schwartz has to be a happy guy. The draft is still a day away and his roster has been upgraded significantly.

It’s a sign of good things to come for the Lions. (Yes, it’s been years since the words “good” and “Lions” have appeared in the same sentence.)

“I like where we’ve been so to speak. I think our philosophy and strategy going in, we were able to accomplish that — pinpoint a couple players that fit exactly what we were looking for and go out and get them,’’ Schwartz said talking about Kyle Vanden Bosch and Nate Burleson.

Then Martin Mayhew went into trade mode which made sense because there were a limited number of unrestricted free agents due to the no-cap year.

“There weren’t going to be as many free agents available and we still had needs. I thought Martin has done a really good job there working some of those later-round picks for guys that have been starters, that have the possibility they may be starters for us,’’ Schwartz said.

Compared to what they went into last season with, this is almost a new team.

“There’s still a lot of room, but I like where we’ve been so far,’’ Schwartz said.
