OK, so the cost for Olave and Penning together + a 2022 sixth round (#194) is:
2022 #18 (1st)
2022 #98 (3rd)
2022 #101 (3rd)
2022 #120 (4th)
2022 #237 (7th)
2023 (1st)
2024 (2nd)
So, the Saints traded away seven (!) picks for three players. Any way you spin this, it is expensive. If Olave and Penning are perennial All-Pros it will be a great trade. If these guys are just OK or, worse yet, wash out or get injured, then these are very bad trades. Seems way too aggressive to me.
Saints have had on the best scouting departments in the league. Use them to find value and system fits in the draft to give the team an infusion of cheap talent. Instead, they were impatient as typical.
All they have left is a 5th and 6th rounder. I guess they figure they'll hit the lottery on undrafted free agents.
