ALLEN PARK — Momentum in sports is a funny thing.

Some believe in it, some don’t.

Certainly there is merit in the argument for it.

So following a dramatic, last-second, comeback win on Sunday will the Lions lose that momentum with a bye weekend?

Not a chance.

“After that game I don’t think you can really lose the energy after that,’’ said wide receiver Kris Durham who caught a 40-yard pass as part of that final 80-yard drive.

The bye comes exactly midway through the season, that’s why Sunday’s win was so crucial Detroit wanted to savor a win and a 5-3 record while on vacation not thinking of what could have been.

“It’s a perfect time for a bye, it’s a perfect time for guys to get healthy and get refreshed,’’ center Dominic Raiola said. “The midway point is an ideal time for a bye and we got it this week.’’

Even a rookie like offensive tackle LaAdrian Waddle thinks the momentum will continue when the Lions get back to practice next Tuesday.

“I think this game creates momentum going into the second half of the season,’’ Waddle said. “I really feel that this team is heading in the right direction as long as we keep our foot on the gas and keep going forward we’ll be fine.’’
