3. The future Hall of Famer has shown no signs of slowing down
I know the NFL is a 'what have you done for me lately' league, and I wouldn't be advocating for Evans if he weren't still playing at a very high level. He was a vital asset in Baker Mayfield's career-redefining season last year and can still take over a game at a moment's notice.
The 30-year-old exceeded the 140-yard mark four times last year, one of which being in the Bucs' Divisional Round matchup with the Lions (and against the Bears, but we don't have to talk about that one). He also scored reached the end zone twice on two other occasions. You could make a case that he was their most valuable player besides Mayfield, as opposing defenses had to commit extra attention his way.
Evans still has a lot to offer at this stage of his career, and whoever lands him will be getting someone eager to build upon their Hall of Fame resume. Likewise, he might even have a chip on his shoulder (he reportedly wanted to resign with Tampa Bay ahead of the season, but they didn't offer him a deal ahead of the opener), so that could be a scary proposition for opposing defenses hoping to slow him down.
I am almost always a proponent of going young at offensive skill positions to capitalize on the prime stages of a player's career. However, Evans is the exception to that rule. He has shown no signs of slowing down, and, whether it be a two-to-three-year deal or a longer pact, the Bears would be very smart to get him into the building.
