So much for flying under the radar.
During Detroit's 35-27 win over Cleveland on Saturday, the Lions offense launched enough fireworks to at least catch the attention of their opponent -- and more are likely to follow suit.
"It's evident when you watch film from 2009 to 2010. I know it's just the preseason, but it's a different football team; I don't care what anybody says," said Browns' veteran quarterback Jake Delhomme after the game. "They're doing it right."
Although Delhomme went on to praise Detroit's defensive unit, which he torched for 152 yards and an 80-percent completion rate, it was Matt Stafford's offense that seems to be putting the league on notice.
The Lions tore through the Browns defense on their first drive, spurred by rookie Jahvid Best's opening play, 51-yard jaunt. Two plays later, Stafford's fade to Bryant Johnson put Detroit on the scoreboard. The drive took just over a minute to complete, but moreover, was a testament to its explosive potential.
Stafford spearheaded an 9-play, 60-yard scoring drive to open the third quarter, using four different receivers while manipulating the Cleveland defense.
He finished 13 of 17 for 141 yards and a touchdown. The second-year quarterback was cautiously optimistic, however, citing his team's second quarter lag (the Lions had two drives killed by penalties and a fumble) as evidence for improvement.
"I have a good feeling, I really do," said Stafford on the offense. "There's obviously certain plays here and there that I wish we could have done a little bit better, but that's the game of football. You're not going to be perfect on every play."
Stafford, along with the rest of the starters, will play minimally, if at all, in the team's final preseason match next week against Buffalo. Regardless, he's ready to flaunt to the remainder of the league what the Browns witnessed first hand.
"I feel like we've done a good job this preseason as a unit, getting out there and executing and playing fast – that's one thing that we wanted to do," he said. "We've done a really good job of doing that.
"Hopefully, (we'll) get some tune-up time in the fourth preseason (game) and get ready to go."
