Tom Brady doesn't believe you can compare the current rosters of the New England Patriots and Baltimore Ravens since so many players are no longer with the teams.

The Ravens have had playoff success against the Patriots, but are no longer coming to Foxborough with the likes of Ed Reed and Ray Lewis.

"Everything's different at this point," Brady said Monday, per WEEI.com. "We can never change anything that's happened in the past, nor can they. You can't bring players out of retirement, they can't either. It's the guys we've got versus the guys they've got, which that's an entirely new team that we have and an entirely new team that they have."
