LOS ANGELES -- One is quiet and unassuming off the field and a menacing pass-rusher within it, a 6-foot-1, 285-pound ball of fast-twitch muscle fiber who is just as good at bulldozing through an offensive lineman as he is at beating one around the edge.

The other boasts skills that are just as dynamic and transcendent as his personality, a 5-foot-11, 198-pound freak of nature with both the hands and the explosiveness comparable to the game's best receivers.

The Los Angeles Rams and the New York Giants face off from London on Sunday, and it also will be a matchup between Aaron Donald and Odell Beckham Jr., the two superstar players who are giving opposing coordinators fits this week.

Three years in, who would you rather have?

In 2014, the Giants took Beckham with the 12th overall pick out of LSU and the Rams followed by plucking Donald out of Pittsburgh with the next pick. Before we examine both, take a look at some of the guys taken ahead of them: Justin Gilbert, eighth to the Cleveland Browns; Eric Ebron, 10th to the Detroit Lions; Taylor Lewan, 11th to the Tennessee Titans. If you've forgotten about them, there's a reason.

Pro Football Reference uses a measure called Adjusted Value to grade the overall significance of each player. From that 2014 draft class, Donald (AV of 31) and Beckham (24) rank first and second, respectively. Zack Martin (16th overall), C.J. Mosley (17th) and Teddy Bridgewater (32nd) are next with a score of 22. Only six of the 12 drafted ahead of Beckham and Donald -- Khalil Mack, Blake Bortles, Mike Evans, Sammy Watkins, Anthony Barr and Jake Matthews -- even crack the top 20.

OK, on to Beckham and Donald.

We know who you'd take if you fancy kicking nets, but this one is all about football -- and we will start with the net-infatuated Beckham.

He might be the most explosive weapon in football.

Beckham didn't play his first NFL game until Week 5 of the 2014 season. Since then, he is one of only three players who rank in the top five in receptions, receiving yards and receiving touchdowns, with the others being the Steelers' Antonio Brown and the Broncos' Demaryius Thomas. Beckham's 28 receiving touchdowns in that span rank first; his 17 100-yard receiving games are tied with Brown and the Falcons' Julio Jones for the most, according to ESPN Stats & Information.

Everyone knows Beckham for the insane one-handed catch he made in Week 12 of the 2014 season against the Dallas Cowboys. But look back as recently as his game-winning touchdown against the Baltimore Ravens on Sunday, the highlight of a two-score game in which he had 222 receiving yards. Beckham uses a rub route to lose his defender, then jukes the safety in the open field and outruns everybody else. That's game-changing speed to go along with those crazy hands.

Said teammate Victor Cruz: "That's him in a nutshell."

Donald plays a far less glamorous position but is without question the best at what he does.

In fact, with J.J. Watt on injured reserve, he might very well be the most disruptive, versatile defensive player in the NFL.

Consider: Since the start of last season, Donald is the only player to rank within the top five in sacks from all three defensive tackle spots, according to ESPN Stats & Information. He has 4.0 as a nose tackle (tied for first), 5.5 as a left tackle (second) and 4.0 as a right tackle (tied for fifth). Donald's 34 tackles for a loss are easily the most among defensive tackles since the start of last year (Geno Atkins is second with 26, and only six interior defenders have half that total).

Donald's 21 tackles for a loss on rushing plays since the start of last year are the most at any position, according to ESPN Stats & Information.

But that's not even his best skill -- it's getting to the quarterback.

According to Pro Football Focus -- the stats site that deemed him the game's best overall player last year, regardless of position -- Donald leads interior defenders with 35 total pressures this season. Nobody else has more than 23. One of those came in Week 6 against the Lions, when he knifed his way around 2015 first-round pick Laken Tomlinson to sack Matthew Stafford in a tie game with less than two minutes left. Another came in Week 5 against the Buffalo Bills, when he plowed through Pro Bowl guard Richie Incognito to sack Tyrod Taylor.

"Power is a combination of force and speed -- force times velocity, strength times speed," Rams defensive line coach Mike Waufle explained. "Aaron's got every bit of it."
