NFL countdown: 70 days remaining and a look at the history of No. 70 for the Cardinals

We are now at 10 weeks left with the countdown to the beginning of the Arizona Cardinals' 2014 regular season -- 70 days.

What is the history of jersey number 70?

Right tackle Bobby Massie is the man wearing that number. He is entering his third season, having been drafted by the Cardinals in the fourth round of the 2012 draft. He started for the team his entire rookie season, as an injury to Levi Brown forced him into action right away. He was awful the first half of the season and then improved, He was one of the best in the league during the final half of 2012.

Entering 2013, he struggled learning the new offensive system under Bruce Arians and lost his job to Eric Winston, who was signed at the start of training camp. He got to play a couple of series against the Texans and otherwise was used as a tackle eligible in some formations. Entering 2014, he is battling for the starting job with Bradley Sowell. He appears to be in the lead entering training camp.

Rex Hadnot wore 70 in 2010 and 2011. He was signed to a three-year deal before the 2010 season and was a backup that first year. He became the starter in 2011 after Deuce Lutui left in free agency and returned after his contract was voided when he failed a physical. He came to Cardinals camp overweight and out of shape and never could overtake Hadnot. Hadnot was released after the season before the team signed Adam Snyder.

We have to go back to 2006 for the next guy, defensive lineman Kendrick Clancy. Clancy had played five years in Pittsburgh as a backup and then landed with the Giants for one season as a starter. The Cardinals signed him to a four-year contract. He started 11 games for the team and then was released in the offseason, as he did not fit in with the plans that Ken Whisenhunt's new staff had for the defense.

In 2005, it was worn by defensive end Anton Palepoi. He played three games.

A player you might remember, tackle L.J. Shelton, wore 70 from 1999-2004. He was a first round pick in 1999 of the Cards. He was the team's starting left tackle from the middle of his rookie year until Denny Green moved Leonard Davis there and Shelton to right tackle. He left uin free agency to the Browns, which seems to have happened a lot.

Before 1999, you have to go all the way to 1992 to find a guy -- tackle Rob Baxley. He was an 11th round pick that year by the Cardinals (remember when the draft was 12 rounds?) and played six games on special teams. He never played again in the league.

From 1986-1990, it was a guy I remember from my first years following the Cards -- center/guard Derek Kennard. He was drafted in the second round by the St. Louis Cardinals in 1986, worked his way into the starting lineup at left guard, starting 10 games. He was the team's starting center for the next three years and then moved to left guard in 1990. He would go on to play seven more years in the league, four as a starter.

Now for the rest...

1987 -- T Victor Perry

1981-84 -- T Art Plunkett

1980 -- T Mark Goodspeed

1978-79 -- DT Keith Simons

1973-76 -- DT Lee Brooks

1972 -- DE John Hoffman

1969-71 -- DE/DT Ron Krueger

1960-63 -- DT/T Don Owens

1958 -- T Jim McCusker

1957 -- DT/T/G Charlie Toogood

1952-56 -- T Jack Jennings (He also wore 50 and 65)

1950-51 -- G Knox Ramsey

What do you all know about the guys before Kennard? Who was the best with 70? My guess is that it would be a battle between Shellton and Kennard, with my giving Shelton the edge because of his position. Any stories or memories you all have of these players?
