5 free agents Patriots could potentially sign before training camp

While the NFL offseason is basically two-thirds of the way over, teams will still be adding players up until training camp in late July.

For the Patriots, two positions come to mind where additions are needed — offensive tackle and tight end.

With the sudden retirement of Jared Veldheer, the Patriots need an insurance policy behind Isaiah Wynn at left tackle, and then with Ben Watson being suspended the first four games, perhaps another veteran tight end would make some sense.

Here are five players to keep an eye on between now and the end of July.

OT Donald Penn- Penn is the best tackle still available. The 36-year-old was released by the Raiders this past March after being their starting left tackle for five years. The three-time Pro Bowler is coming off playing just four games last season due to a groin injury, but it is a rarity to have such a solid player still available this time of year. Perhaps he could be worth a shot as a player looking to play for a contender.
