I see Duke and UofL (our rivals of course lol).
Snider, King, Adel, Spalding, and Mahmoud do not scare me and their bench will rely on Freshman who aren't really top level guys other than that big man they got...a Pitino team relying on freshman does not sound scary considering how freshman play under him. Losing Johnson and Mitchell hurt...but they also lost Mathiang and Matz in the post..combined with Johnson they will be paper thing in the post. They'll be ok with a senior PG, but not elite.
Duke will be relying on a freshman point, who really is not a Coach K style PG and that will not be good for them. They have some talent in the starting 5, but their bench options look thin. They aren't deep, ultra talented or more experienced than usual so I think they could struggle.
Yep, Louisville losing anyone to early entry is bad news for them, because Pitino relies on a system of upperclassmen who have learned to play his style in order to win games. So, losing Mitchell and Johnson hurts them tremendously. They also lost Mathiang, Stockman, and Hicks from that team. Returning Adel is significant, because they'd really be hurting for scoring without him. Remember, this was a Louisville which struggled to score last season losing 3 of its top 5 scorers. Louisville doesn't rebuild, well, actually that is what they do. They must rebuild and their building blocks are incoming freshmen, which Rick doesn't get production from. As you say, it will be PG Snider, SF Adel, PF Spalding, and C Mahmoud. I don't know who will play the 2 for them. VJ King can shoot but can't really handle the ball well. He could play the 3. Adel might be their best bet, but he's not a great ball handler, either. Mitchell leaving as a sophomore hurts them badly.
As for Duke, I see several publications calling them a winner after the early entry lists have been finalized, but I don't see that. I'm sure I'm biased, but they lost a ton of talent and experience from this last team. Not only did they lose Tatum, Giles, Jackson, and Kennard to early entry, they also lost the guy who has been their consistent anchor for several years inside in Jefferson, and they also lose Jones, who had become a solid defender and was always a reliable shooter. I think it's going to be the Grayson Allen show again, and I don't see it going as well. Kennard overshadowing Allen was a good thing this past season. I like the look of Duval, Carter, and Trent, but are any of those guys great scorers? If Coach K continues 4 out, 1 in, how will Carter, Bolden, and Jeter all play? Looks like it will be a line-up of PG Duval, SG Allen, SF Trent? PF Jeter/Carter and C Bolden. 3 starting freshmen? I'm sure our resident Dukie will set me straight on that line-up. I'm sure they were counting on Knox coming in and playing the wing opposite Allen and they may have been holding out hope for Bamba to play center, but those ships have sailed.
