I think signing Maclin is a home run. I won't compare him to Wandale, because that isn't fair. Wandale is a pro. But Maclin is an upgrade compared to TRob, and that is a compliment.
Key will almost certainly remain at the "x" position in our starting lineup. The competition will help him, as will the coaching change. While 2023 has been a season of regression for Key, generally speaking, OTOH Dane turned it around in November. The regression has a lot to do with why Woodward is no longer here. Dane has immense upside. He is still potentially an NFL receiver, and I look for our next WR coach to clean up his route running and approach and make a pro out of him.
Cottrell is an important add, but he has one career catch. Both Cottrell and Porter have great frames and tools but are way behind Key and BB in development even though our starters also need more development. ABS will understudy Maclin but ABS has a big future. He is another who was done no favors by Woodward.
I look for one more WR to be added from the portal. Our coaches are working hard to hang onto Hardley Gilmore, who will become a great SEC player at UK. I was looking at David Washington's offer sheet, and it isn't exactly chopped liver either.
