1. Tight end is back on the table in the NFL draft
The last reason Trey Burton getting released was not highly anticipated was that Matt Nagy had talked extensively about using multiple tight ends. Two, even three tights on the field, is how Nagy likes to expose teams.
So, when the Bears signed Jimmy Graham, it could have been argued that an older Graham and a banged-up Burton could split time, and see time on the field together. It could preserve both, and give Nagy the depth he coveted so highly.
With Burton in the mix on top of Graham, Harris, and others, there was too much depth to draft a tight end. Now, they could find a compliment to Graham at tight end throughout the draft.
There are plenty of options to choose from, and picking at 43, there may not have been a tight end drafted yet. Do the Bears want to start a tight end run? Just because they have Graham, do not count it out.
