Sounds like Maclin's a bit overrated here because of that last big year in PHI and that big contract. He had the HAS in 2015 and the groin issue last season that slowed him down a bit. That's probably just regular NFL wear-and-tear, but it's always hard to be sure. He's a better receiver than Terrence is, and they're probably comparable blockers pound for pound, though Williams is a bigger guy.
Overall, he's be an upgrade, but probably not one worth what he'd likely cost.
I'm happy with our WR situation right now. Why can't the Chiefs inexplicably cut a decent DL or something?
