Cards Mailbag: Free agency begins -- Part 2

Welcome to #CardsMailbag, a weekly installment that allows you to ask me questions about the Arizona Cardinals throughout the week via Twitter @joshweinfuss. I'll answer them every weekend during the offseason. Make sure to use the hashtag #CardsMailbag.

@joshweinfuss Every team knows how much cap space they need for their draft picks based on their draft slot, and I think Keim and cap guru Mike Disner are smart enough to keep that money free. Like I said earlier, I don't see the Cardinals trading up because Keim doesn't like to lose picks, he likes to stockpile them. And as for trading for Adrian Peterson, again, it'll all depend on what the Vikings want and if the Cardinals feel he's worth a long-term investment of draft picks (the likely currency for him).

@joshweinfuss You're right, Dwight Freeney is not a bad guy on third-and-long, but I don't see the sense in signing someone just for big leads. Do you? I think they found that person in Cory Redding. Freeney could be a good add next week, however, for cheaper than what he'd cost during the first week of free agency. But while he could still be an effective pass-rusher, the Cardinals need to be careful of not adding too many older vets. In the end, I don't see it happening.

@joshweinfuss From what I've seen and read about former Georgia running back Todd Gurley, I think he'd be a solid fit in the backfield. Arizona needs a tough runner like that to complement Andre Ellington, but my main concern about picking Gurley is how long it'll take for him to recover from ACL surgery. He may just be getting healthy for the start of training camp, which means he'd have missed all of OTAs and minicamp. And in Bruce Arians' offense, that could set a player back a bit -- just look at Troy Niklas last season, who missed a significant amount of time because of his injuries. But if Arizona takes a chance on him, I can see Gurley being a factor after the first month of the season.

As for upgrading the tight end position, the Cardinals seem to like the trio they have now with John Carlson, Darren Fells and Niklas. They could add a fourth tight end either through the draft or after teams cut guys in August.

@joshweinfuss If he's around when the Cardinals draft at 24th, I don't know how they don't go after him. I think he has the size and speed that Arizona needs to share a backfield with Ellington. He could handle a full-season workload without breaking down while Ellington could be the main passing option out of the backfield.

@joshweinfuss I think Greg Hardy is basically out of the question. I don't see this franchise pursuing him. As for center Stefen Wisniewski, I'm skeptical Arizona signs him and here's why: If they really wanted him, he would've been a priority during the first few days of free agency. I think Arians and Keim believe they have the next center on the roster or they're going to target one in the draft. They have the best scouting report possible in Jared Veldheer, who played on the same line as him in Oakland from 2011-13. As for Peterson, read back. I've addressed him a few times.
