It's true that Jackson was bad defensively, but with a team like this, who really cares? We were a train-wreck on both ends of the floor and Jackson would have made us much, much better offensively. There is no way you could have watched him play and not seen an all-conference caliber prospect.
Enoch was one of the worst defensive players I have ever seen at UConn, so in his case it is less clear how much we missed him. He did have incredible tools on offense and almost certainly would have given us more than Onuorah even by accident. At the very least, he would have made us more watchable.
Durham hurt the most because he had game-changing potential on both sides of the court. Whether he was ever going to get there after two knee surgeries was anybody's guess.
I understand the statistical argument that these weren't good players, but anybody who thinks we didn't miss them like hell this season needs their head examined in my opinion. We're talking about a completely different level of talent than Polley, Whaley, and Carlton.
