This will pain some to hear, but I think the reason why we are hearing the rumors linking the Habs to the likes of Frolik and Beleskey is because of system fit. It was reported the Habs tried trading for Beleskey before. They hoped DSP could bring what Beleskey brought. So far DSP hasn't proven he can solidify a 3rd line role. On the other hand, Frolik plays a solid 200 ft. game and is a versatile forward. He is in his prime and could fill a top 6 or top 9 role quite readily.
My only gripe with these players is that they don't really replace anything we don't already have. We don't need more 15-20 goal scorers. (Albeit you can argue we need to replace the production that was forecasted for Parenteau). There are perhaps too many bottom six options for the Habs when accounting for the likes of Bournival, Thomas, DLR, DSP, Flynn, Weise and Prust. I am not seeing the logic in the supposed pursuit of Beleskey unless some of these guys are moved, or not in the plans for the big club.
I having nothing to substantiate this, but I have a feeling Prust will be traded this summer. I think the brass was turned off by his antics, and his play clearly regressed. He is loved in that locker room though....
