SCOUTING REPORT: SUMMARY
Siaki Ika is a huge classic prototypical nose tackle possessing all the size and strength you hope to see in the position. He is a serious space-eater and requires double teams to control his bull rush, and since his transfer to Baylor has been a very productive dominating player in the middle of the line. He however has never displayed elite tackling ability and was billed as an impressive athlete with surprising quickness for his size this size, but this didn't show during his combine workout - as he put up pretty pedestrian numbers, which may have impacted his stock.
Overall it's difficult to give Ika anything higher than the third-round grade in the 2023 NFL draft although he may be overdrafted due to the lack of quality NTs in the class.
