The Patriots may have put together the most eventful four-player draft class in history over the weekend by trading away all of their original picks and then trading up, down and all around.

Bill Belichick’s previous 17 draft classes averaged nine players, and he has reached double digits on seven occasions, including a high of 12 players in 2009 and 2010. Prior to this weekend, Belichick’s smallest draft class had been a six-player squad in 2002, and that was actually a really good group that proved high quantity isn’t always necessary for high quality.

So with the Patriots’ small group in mind, let’s examine the five most important things the team unveiled over the weekend.

1. Living on the edge

The Patriots followed through with their offseason priority to get younger at defensive end, drafting Derek Rivers in the third round (No. 83 overall) and Deatrich Wise in the fourth (No. 131). Rivers was one of the more intriguing players at the loaded position because he’s got plenty of long-term potential but may take some time to realize it after coming from Youngstown State. Wise was viewed as a possible first-rounder after a booming junior season, but injuries destroyed his senior year. If Rivers pans out and Wise stays healthy, they’ll join Trey Flowers as the future faces of the front line. The draft also punctuated an offseason youth movement that included parting ways with Jabaal Sheard and Chris Long and bringing in Kony Ealy.

2. Tackle projects

The other half of the Patriots’ draft class included tackles Antonio Garcia (third round, No. 85 overall) and Conor McDermott (sixth round, No. 211). Garcia is an athletically gifted prospect who needs time to grow, which is perfectly fine because starters Nate Solder and Marcus Cannon are returning. It’s possible Garcia could push Cameron Fleming as the top swing tackle in 2017, and the addition of Garcia likely spells the end of LaAdrian Waddle’s tenure. McDermott is a practice squad candidate, so don’t overreact to the two-tackle class as a way to overhaul the position for this upcoming season. However, Solder is 29, entering the final year of his contract, has a history of concussions and, far more importantly, has a priority off the field with his son’s cancer fight. It’s worth wondering how much longer Solder will continue to play. Fleming is also back with a one-year restricted free agent tender, so he could be gone after 2017. At the very least with Garcia, the Patriots are upgrading their depth at tackle, which will be significant if Solder and Cannon can’t get through 2017 as unscathed by injuries as they were in 2016.

3. Twenty-somethings

This was viewed as an overly impressive draft class, especially on defense, so it was definitely a surprise the Patriots only used four picks. But don’t take that fact to be an assumption that Belichick hated the draft class. The slim class was likely more about opportunity than anything else, particularly after they traded away picks in the first four rounds for Brandin Cooks, Ealy and Dwayne Allen. On the flip side, Nick Caserio made it sound like the Pats would use their 20 open roster spots on undrafted free agents. They already went to work on that, and the prized signing appears to be BYU linebacker Harvey Langi. Tight end Jacob Hollister is another intriguing player, and the Pats also added his twin brother, Cody, so that’ll be something. Wide receiver Austin Carr may cause some rubber necking from the coaching staff, but he’ll need to benefit from an injury to make the team. With such a loaded roster, who knows how many of these rookies can crack the roster, let alone contribute.

4. Second guesses

The draft is always about second guesses, either in the immediate future or years down the road. Rivers looks like a good pick, but by trading down, the Pats missed a run on defensive ends that included Jordan Willis, Chris Wormley, Daeshon Hall, Tim Williams and Tarell Basham. The Pats also took Wise over cornerback Desmond King, whose fall to the fifth round was one of the biggest surprises of the draft. Tight ends Jake Butt, Jordan Leggett and George Kittle were also there for the taking at No. 131.

5. Standing Pat

Heading into the draft, the greatest question surrounding the Patriots involved the fates of cornerback Malcolm Butler and quarterback Jimmy Garoppolo. Neither was even close to being traded. The Saints were never in the ballpark with an acceptable offer for Butler, and it sounds like the Patriots never even unveiled Garoppolo’s price to the Browns, who basically had to make a proposal that would be so absurd the Pats couldn’t refuse it. The speculation over their future won’t end considering they’re both signed through 2017. Will a team without a quarterback make a summer push for Garoppolo? Will Belichick surprisingly trade Butler like he’s done with other past contributors? Both may very well remain in town, but don’t expect much peace of mind until the midseason trade deadline passes.
