Last week I looked at changes in the rosters in the B1G East so far in the offseason. Today we will do the same for the B1G West. The NFL Draft declaration date has come and gone, so we have some more clarity, though transfers are still in the process of deciding. As I said with the East piece, my plan is to come back through in a couple months and take a look at how the dust settled on these respective rosters. Purdue EXITS The Boilermakers have had a busy offseason, with their most notable exit being coach Jeff Brohm. With a new regime in, you'd expect quite a bit of turnover and there's plenty of it. Graduation/the NFL has taken all three of their stars in the passing game, QB Aidan O'Connell, WR Charlie Jones, and TE Payne Durham, as well as a huge chunk of their pass defense, starting corners Cory Trice and Reese Taylor, as well as HSP Jalen Graham and LB Kieren Douglas. They will be returning most of the OL and lead back Devin Mockobee, but that's a lot of experience and production to make up, before we even get into the portal subtractions. To the portal the Boilermakers lost Spencer Holstege, a starting G for this year's team, as well as three useful pieces on the defensive line, Lawrence Johnson and Branson Deen, who were starter-ish rotation pieces at defensive tackle, and starting DE Jack Sullivan. All four of those players opted to pack their bags for warmer weather, with Deen opting to head to Miami, Johnson to Auburn, Holstege to UCLA, and Sullivan to rival USC. Reserve RB Kobe Lewis bailed for FAU as well, and then an assortment of bench names I am not familiar with are in the portal as well. It's going to be a pretty different Purdue team that shows up in Ann Arbor to play the Wolverines in the fall than the one we saw in Indianapolis a month ago. ACQUISITIONS Well we can start with the new HC Ryan Walters, who is replacing Brohm. Walters, who turns 37 tomorrow, is considered a top young mind in coaching circles after presiding over elite defenses back-to-back seasons at Illinois, where he had minimal talent to work with. Seemed like a smart hire to me and he's reshuffled the coaching staff, bringing new DC Kevin Kane with him from Illinois (he was the associate head coach and OLB coach) and hiring new OC Graham Harrell, of Texas Tech QB fame from the late 2000s, away from West Virginia. Kane will help him rebuild the Purdue defense, while Harrell will ensure continuity with Brohm's Air Raid scheme. All three of these coaches are under the age of 40, so this is an exceptionally youthful staff. The biggest question for the Boilermakers with Aidan O'Connell leaving is what will happen at QB. Their big add out of the portal was QB Hudson Card from Texas, a high 4* prospect in the 2020 class who got passed over for Quinn Ewers in Austin, but played some when Ewers was injured this past season and did fine. Card seems to be the favorite to start, though Purdue managed to keep Brady Allen, their Class of 2022 QB who was a solid 4* himself, in the fold. Allen originally had his name in the portal, but pulled it out to return to Purdue, suggesting there will be a legitimate QB competition here. Elsewhere Purdue has added a few supplemental pieces, Isaiah Nichols (DT) and Anthony Brown (S) from Arkansas, the former being a middling rotational piece on the DL, while the latter got a redshirt as a true freshman this past season. They also got interior OL Jalen Grant, a two year starter at Bowling Green, to jump on board. None of these strike as particularly high impact additions, and I would expect them to add some more as the next few months roll along and the new staff gets their feet under them properly. [AFTER THE JUMP: more or less chaos]
