The Browns gave up a 3rd round comp pick for Collins. If they hadn't re-signed him, they'd be in line for a 3rd round comp pick next season. That's not exactly free spending. The speculation in the media is coming from Pats' shill Jason LaCanfora and its sole purpose is to drive up value for JG. Mary Kay Cabot simply recycled his "report" of Browns interest because, quite frankly, that's all she does.
Also, I'm from Cleveland and I do know a lot of people there. Some are even in the know with the Browns. I can give you this much: the Browns haven't even decided on their direction concerning QB in 2017 and that includes any decision on whether or not to pursue a trade for JG. Anyone saying they know what they'll do in this regard, be it JLC, MKC or anyone else is full of ****.
From my personal observation, the thought of giving up the 12th pick for a second round prospect with precious little gametape and who is on the last year of his rookie deal would be beyond asinine. It's just wishful thinking by Cheatriots fans and media hype coming from the team.
