"Broberg isn't worth the price"
Offer Sheets 101 - if you offer fair value, the other team will match. The team that offer sheets is forcing a trade, so they need to find an angle to which it works out.
Also, I wonder if the Blues are going for a psychological attack here with two offer-sheets. As in, are they hoping to "force" the Oilers into thinking they have a choice to make between the two players, and Holloway being more fair price, get Broberg?
After all, Broberg is a former 8th overall, 6ft4, 212 lbs, only 23, and produced good offense in the AHL. I haven't seen him play much, but on paper, seems like a GM's wet dream for 4M and a 2nd pick.
