Can you name a successful punt returner at the pro level who never returned a single one in college as well??? It's definitely not smart to not care about the punt returner but about the #6 or #7 receiver on the roster who will most likely be inactive for all games.
Definitely, you say? That's debatable. If you have a great offense, you don't need a great punt returner. They are a luxury. All you need is a guy who can reliably field the ball and let the offense do it's job. Hell, give the job back to Cobb. He's by far the most experience returner on the team. I'd rather do that than keep Davis over any of our three rookies unless one of them just completely bombs over the next 2 weeks.
Now let's dispel with the myth that Davis is one of the elite returners in the NFL. Being a great returner entails FAR more than just yards per return. He has to be fearless and make solid split-second decisions. How many times did we watch Davis field punts not only inside the 10 yard line, but even inside the 5 yard line? How many times did we watch him call for fair catches with nobody within 10 yards? How many times did he let the ball go over his head when he shouldn't have? Let's do some objective analysis on Davis's value as a punt returner. Obviously he was 3rd in the NFL in yards per return at 12.0. But let's look at how many yards he averaged every time he fielded a punt and compare him to the other guys in the top half of the league in yards per return.
The format here will be: Name: <punts returned>-<punts fielded>-<yards>-<percentage of punts returned>-<yards per punt fielded>
1. Agnew: 29 - 45 - 447 - 64.4% - 9.9
2. Cooper: 32 - 40 - 399 - 80% - 10.0
3. Davis: 24 - 46 - 289 - 52% - 6.3
4. Campanaro: 26 - 47- 291 - 57.8% - 6.5
5. Mickens: 27 - 46- 287 - 58.7% - 6.3
6. Tate: 20 - 26 - 193 - 76.9% - 7.4
7. Sherels: 39 - 63 - 372 - 61.9% - 5.9
8. Benjamin: 27 - 52 - 257 - 52% - 4.9
9. Cohen: 29 - 44 - 272 - 66% - 6.3
10. Taylor: 30 - 46 - 281 - 65.2% - 6.1
11. Barner: 27 - 42 - 240 - 64.1% - 5.7
12. Switzer: 29 - 39 - 256 - 74.3% - 6.5
13. McKenzie: 21 - 39 - 183 - 53% - 4.7
14. Amendola: 27 - 45 - 231 - 60% - 5.1
15. Jackson: 32 - 43 - 290 - 74.4% - 6.7
16. Hill: 25 - 32 - 204 - 78% - 6.4
Davis fielded 46 punts last year. He returned the ball 24 times total. That's 52% of his touches, which was one of the lowest percentages in the league. That tells me two things: First, he's not a natural at the position. Two, he is either afraid to take a hit or he cherry picks his returns when the blocking looks good. Either way, his yards per return does not equate to his value on the field as a punt returner. He left a lot of yards on the field. Even though his YPR is right behind Cooper, it's clear he's not even close to being in the same league as the top two guys. The only guys on this list I would place him ahead of would be Travis Benjamin, Danny Amendola and Isaiah McKenzie. Sherels, Barner and Taylor also averaged less, but they returned a much higher percentage which indicates to me that they left fewer yards on the field and made fewer ill-advised fair catches. Don't think the Packers aren't well aware of this too.
The bottom line is this: Davis was only about 12th best in terms of overall production. As a returner, with everything the position entails, he's only marginally above average and not worth exposing any of our high-upside rookies to the waiver wire or PS.
