Yep. They mix real interest with fake interest

They aren't about to reveal their actual intent by only bringing in guys they are serious about. They also bring in ringers that could make sense, but they aren't ever going to be the guys, and this to throw off the scent from teams who might want who they want, or to convince a team to trade up to get around them, pushing a guy down they do want.

Bottom line: pay no attention because we'll never know which is which.
