Ehh, I think athleticism is different for different sized players. Obviously Carsen is very athletic but Nojel is incredibly athletic for being 6'7 and being able to, what appears, a lot of the same things. What may end up being a huge advantage next season is that 1-4 with Nojel, Carsen/PJT, Mathias, and Vince...you are going to be able to guard the 1-4 very effectively with either athleticism or with intelligence. That gives a lot of flex to what Painter would like to do on the defensive side. Having Nojel, who can body up against large 2's and 3's...and even a player like Wagner...gives Purdue the ability to not only pressure the ball more off the three point line (that is where Kansas really turned the game in the second half...when they pressured Purdue 5-10 feet off the arc).
I think for what we have seen the last few years manifest itself in the college game, the best lineup for what many fans have been clamoring for next season would be:
G: C. Edwards (6' 190)
G: Mathias (6'4 200)
G: Eastern (6'6 210)
F: V. Edwards (6'8 225)
F: Haarms (7'2 225)
In this lineup, you have length and size but also enough athleticism that won't get you burned by teams like ISU or Michigan this past season. The advantage of this lineup is that outside of Eastern, all the players have been with Purdue for a season as well. I could very well see this being the second lineup outside of the obvious starting lineup being:
G: PJT
G: C. Edwards
G: Mathias
F: V. Edwards
C: Haas
In what I expect to be the first substitution pattern, you have Haas getting a break early in the game for a majority of minutes from roughly 12 minutes to the 4 minute timeout along with sliding Nojel in to create a mismatch on the wing against smaller players. The lineup with Nojel will create most of the issues for other teams in that if you defend Nojel with a smaller player, he can take them inside which leaves a slower player for Vince to take off the dribble. If you slide a more athletic player against Vince, you risk putting a slower player on Nojel/Mathias who have shown the ability to get to the rim and either shoot or pass out (seriously, watch Nojel's highlights...he has great vision when getting in the lane at times).
