As memory serves, health was one of the big factors for Warren being ranked ahead of Loveland, but most prognosticators had them roughly within 5-10 spots of each other. Loveland was also seen as more of a project since he was a stretch the field type of TE, whereas Warren was more in the Cole Kmet mold (which people mentioned as a possible justification for taking Loveland over Warren).
This draft was also really muddled where the Bears were picking, since the top 3 OTs were off the board, Graham was popped earlier than expected, and Jeanty went to the Raiders. There wasn't an obvious slam dunk pick there.
I kinda think this debate misses the mark, though, since 3 out of the 6 healthy inactives yesterday consisted of two 2025 2nd round picks and the 2024 3rd round pick (which was the Bears' third pick in the draft). You can justifiably debate Loveland/Warren either way, even in retrospect, but those guys should at least be suited up at this point of the season given how high they were selected.
