It’s been eight years now, so you can be forgiven if you’ve forgotten, but there was a time when Reggie Bush wasn’t just expected to be a good NFL player, wasn’t even expected to be a great NFL player, but was expected to be a transcendent NFL player. When Bush was running wild at USC in 2005, people talked about him like he was going to be some combination of Barry Sanders and Gale Sayers in the NFL, a player who had the talent to be the NFL’s best running back, the NFL’s best slot receiver and the NFL’s best kick returner, all in one package.

It didn’t happen, for a variety of reasons ranging from the fact that the team that drafted Bush, the Saints, really didn’t need him to be an every-down running back, to the fact that it was basically impossible for anyone to live up to the kinds of expectations that were on Bush coming out of college.

But what has happened in this, Bush’s eighth NFL season and first with the Lions, is that we’re finally getting the Reggie Bush we’ve been waiting for. The Lions have the right offense to take advantage of Bush’s skills, both as a runner and as a receiver, to get him the ball in space and to let him cut and spin and start and stop and hurdle and sprint to the end zone.

Bush did all of that and more on Sunday against the Bears, a game that might have been the best of his NFL career. Bush had 18 carries for 139 yards and added four catches for 34 yards, but those numbers don’t do justice to how electrifying he was. Bush’s 37-yard touchdown, on which he took a handoff up the middle, ran past defensive end Cornelius Washington before bouncing to the outside, hurdled safety Major Wright and then outraced cornerbacks Tim Jennings and Charles Tillman to the end zone was one of the most beautiful plays of this NFL season.

The Lions have made Bush their featured back in the running game and are giving him plenty of opportunities to carry the ball, and they’re also throwing him a lot of passes, not just out of the backfield but lined up as a slot receiver. Opposing defenses give so much respect to Lions receiver Calvin Johnson that Bush isn’t going to see many eight-man fronts, and he’s going to have a lot of room to make plays all season. Bush has only played two and a half games so far because he missed half of Week Two and all of Week Three with a knee injury, and durability will have to be a concern for Bush in Detroit, just as durability is a concern for any running back who gets the kind of workload the Lions are giving Bush. But if he can stay healthy the rest of the way, he has the potential to lead the league in yards from scrimmage, and lead the Lions to the playoffs.

Bush was my favorite player in any game on Sunday. Here are my other thoughts from Sunday’s games:

The Jets need to do more pushups. With all the Jets’ penalties last week, Rex Ryan implemented a new policy that whenever anyone committed a penalty in practice, everyone had to do pushups. It didn’t work. The Jets committed 10 more penalties on Sunday. Through four games this season, the Jets have committed 44 penalties, putting them on pace to commit 176 this year. The all-time NFL record is 163 penalties in a season, set by the Raiders two years ago.

Chip Kelly needs to be Chip Kelly. The reason I was so excited about Kelly leaving Oregon to coach the Eagles was that we had never seen a coach like Kelly in the NFL before. But while the Eagles’ fast-paced offense is fun to watch, for the most part I see Kelly coaching in Philadelphia like he did in college. At Oregon, Kelly wasn’t afraid to go for it on fourth down from anywhere on the field. But on Sunday in Denver, when the Eagles had a fourth-and-6 at Denver’s 37-yard line while trailing 21-13, Kelly took a delay of game penalty and then punted. Why not go for it? You’re playing the best team in the NFL on the road. You’re going to need to take some chances to pull the upset. I didn’t see the Eagles taking many chances on Sunday, when they punted four times, attempted three field goals and never went for it on fourth down despite trailing all game. Although the Eagles went for it on fourth-and-1 and got the first down on their first drive of the season, in the opening Monday night at Washington, Kelly has gone for it on fourth down just once since that very first drive. It’s disappointing to see Kelly turn into a conventional, risk-averse NFL coach.

Sean Lee is that rarest of creatures, an underrated Cowboy. Usually players on America’s Team are overhyped, but if anything Lee, a linebacker in his fourth year in Dallas, doesn’t get enough hype. Lee’s 2012 season was cut short by a toe injury after six games, but this year Lee is looking healthy and faster than ever, as he displayed on his 52-yard interception return for a touchdown. Lee did get beaten in coverage on a touchdown by Chargers tight end Antonio Gates, but that play aside he’s having a strong season, and if he stays healthy he’ll make his first Pro Bowl.

Kiko Alonso leads the league in interceptions. Alonso, the Bills’ second-round draft pick out of Oregon this year, came into Sunday’s game with two interceptions on the season and added two more of Joe Flacco in Sunday’s win over the Ravens. He now has four, tied with Patriots cornerback Aqib Talib and Titans cornerback Alterraun Verner for the most of any player in the NFL through four weeks. In addition to his interceptions, Alonso has been a tackling machine. The Bills look like they got a keeper. Alonso’s college coach Chip Kelly should have drafted Alonso in Philadelphia — the Eagles need all the help on defense they can get.

As usual, the Super Bowl hosts stink. The Super Bowl will be played in New Jersey at the end of this season, and we won’t be having any talk about a team playing a Super Bowl on its home field, as the Giants are 0-4 and the Jets are an ugly 2-2. This is probably more a coincidence than anything else, but the Super Bowl host team almost always has a lousy season. No Super Bowl host team has even made the playoffs since Tampa Bay in 2000, and not only has no team ever played in the Super Bowl on its own home field, but no team has ever even reached the conference championship in a postseason when the Super Bowl was on that team’s home field. The Cardinals host next season’s Super Bowl, the 49ers the year after that and the Texans the year after that. Sorry to fans in Arizona, San Francisco and Houston, but you can probably pencil in a disappointing season for your teams when the Super Bowl is coming to town.

Adrian Peterson breaks long runs like no one else, ever. Peterson’s 60-yard touchdown on Sunday was his 12th touchdown of 60 yards or more. No one else in NFL history has had even 10 touchdown runs of 60 or more yards. Jim Brown, who had nine 60-yard touchdown runs, is second in NFL history.

Peyton Manning is amazing. I know I said earlier that Bush was my favorite player in the NFL on Sunday, but I should probably add that I could say that about Manning every Sunday. Manning completed 28 of 34 passes for 327 yards, with four touchdowns and no interceptions against the Eagles, and he didn’t even play in the fourth quarter. His 16 touchdown passes are the most ever for any quarterback four weeks into the season. The Broncos have scored 179 points through four games, putting them on pace for 716 points this season, which would obliterate the 2007 Patriots’ NFL record of 589. This may be Manning’s best year yet — an amazing thing to say about a guy who has four league MVP awards.
