DT seems the most likely. The likelihood that Star (1) holds up after opting-out last year is suspect; and/or (2) plays like he did previously is also suspect. Hoping on Harry is also just Hope, and he is also injury-prone. With an 18 game season, if they have their eye on a DT, the time to move is now.
If there isn't a DT they like now, then I agree, just emergency money, but Bean may see a DT "potential emergency" and "potential replacement" now.
