New England Patriots quarterback Tom Brady believes that his side's talented rookies still have it all to prove in the NFL.
The Patriots overhauled their wide receiver position in the off-season allowing Wes Welker and Brandon Lloyd to leave, replacing them with the inexperienced trio of Aaron Dobson, Kenbrell Thompkins and Josh Boyce along with Danny Amendola.
Brady told radio station WEEI: "The thing with NFL football is you need to perform on a daily basis, and during the season on a weekly basis in the games. That's why guys stick around for a long time, because they can consistently perform at a high level.
"It's hard to tell with any of the rookies whether they're able to do that yet. They've obviously made it this far and they've gained the trust of coach Belichick to have them on the team.
"He thinks that they're able to help us win games, which is why we're here and why we have the job that we have, is to win."
New England face the Buffalo Bills in their season opener on Sunday.
