I think there is a lot to consider when it comes to Wills. First the Browns have no 1st round draft picks for years. Hopefully the Browns will do no worse than middle of the pack in terms of W's so that would leave you with a mid second round pick to address the LT position at best in the draft. At that point in the draft at a position highly valued and in high demand, the odds of drafting an upgrade to Wills would be a high risk proposition.
Better players at the position in the FA market would cost a boatload more than that 5th year money. And last but certainly not least Browns fans were so spoiled by Joe Thomas being here, that as you mentioned, they've forgotten what not having a legitimate LT looks like.
