ALLEN PARK — Martin Mayhew describes running back Jahvid Best as “lightning in a bottle.”

That explains why the Lions general manager worked a trade with Minnesota to move up four spots to draft Best with the 30th overall pick in the first round of Thursday’s NFL draft.

The Lions gave up their second round pick, one of their seventh-round picks and they swapped fourth-round picks with Minnesota.

“We needed a running back, we felt like there were three running backs in this draft we really liked. The other running backs got drafted and we felt we could move up there and get Jahvid Best and we made that move,’’ Mayhew explained.

It was a banner night for the Lions who drafted defensive tackle Ndamukong Suh with the second overall pick.

They seriously upgraded their defense and offense in a four-hour span.

Coach Jim Schwartz was thrilled with both moves.

And he thanked owner William Clay Ford for making the financial commitment that allowed them to take a second first-round player. For comments from Jahvid Best, check back on Lions Lowdown later.
