Both the Nittany Lions and the Boilermakers are still trying to find their footing late in the season. A win gives Purdue something to build on for next year, while a PSU win would at least get the Lions back on some kind of track before the final two games.
Here are five things to keep an eye on:
1. Two true freshman QBs with lots of potential. OK, you already know plenty about Christian Hackenberg and how he's making a strong case for the Big Ten freshman of the year award. But Purdue's Danny Etling could have a bright future ahead of him, too. The Boilermakers are struggling, but Etling said -- despite the numbers -- he's improving every week. He was a four-star recruit last season, the Boilermakers' highest-rated prospect since ESPN started keeping track, and he's been the starter since Week 6. He has thrown five interceptions to four TDs so far this season, but his best football is ahead of him. Same goes for Hackenberg. Watching these two players Saturday should be like catching a quick glimpse of the B1G future.
2. Allen Robinson nearing another school record ... again. No, this isn't a misprint. He broke Bobby Engram's single-season receiving mark of 1,084 yards last week -- and he could set the single-season receptions record against Purdue. Robinson set that record last year with 77 catches, and he currently boasts 73 receptions. He's the only Penn State receiver to reach the 70-catch mark, and no PSU wideout has ever reached the 80-reception plateau. Expect more of the same from Robinson; he's making history just about every week now.
3. Running wild over Purdue. The Boilermakers have allowed 200-yard rushing games five times so far this season, as they're ranked No. 111 in the country in rush defense. That means big games could be in store for both Bill Belton and Zach Zwinak. It's been difficult to predict lately who'll handle the heavier workload, but both are likely to see plenty of time in the afternoon. Zwinak can run on the inside and blow over defenders for extra yards, while Belton's cutting ability has improved greatly since last season. Both players should be able to pad their stats against Purdue's dismal run defense.
4. Third-down defense. The Lions' defense took a step back last week, as they allowed the opposition to convert on 7-of-10 third downs during the first half of last week's game. They couldn't get off the field, and that was a big reason they were manhandled in the first two quarters -- so it's worth keeping an eye on that same down Saturday. The good news for Penn State is that Purdue is among the worst in the country (notice a trend?) and ranks No. 114 in terms of converting third downs (30.6 percent). So, if PSU can't stop Purdue on third down, then it probably won't be able to stop future opponents Nebraska and Wisconsin.
5. New PSU player roles? LB Ben Kline didn't open the season as the starter, but he started the last two games and seemed to be making a lot of progress. He's out for the season now, so it'll be interesting to see if this corps takes a step back against Purdue. Stephen Obeng-Agyapong and Nyeem Wartman will likely compete for his spot, just as they did before Kline earned the starts, but Bill O'Brien also mentioned that true freshman LB Brandon Bell should see an increased workload. On the offensive side of the ball, O'Brien told reporters to expect to see more of redshirt freshman wideout Eugene Lewis, who made an outstanding 54-yard TD catch in Week 1 ... but has only accounted for 71 yards since. If Robinson leaves early for the NFL, Lewis could be PSU's top wideout next season.
