"In all honesty, in all fairness, how can you take a guy out of the game who's been playing so well?" Vick said Thursday in his weekly radio spot on WIP-FM, via CSN Philadelphia.
"I've been in this stage before, and I know what it's like. I understand the position that this team is in, and the one thing I never want to do is be a distraction or put our team or our coaches in a position where they feel like they're not doing the right thing or I feel like they're not doing the right thing."
Vick, dealing with a hamstring injury, understands the situation. He got his chance to start for the Eagles under a similar situation, when he replaced an injured Kevin Kolb in 2010.
"(Foles) had an opportunity to learn from me this year and last year and just sit behind me and pick my brain, and he also went out and played the game, and now he's just taking that and everything is unfolding for him," Vick said.
Foles has been stellar since taking the starting reins, most notably his 16 touchdowns to zero interceptions. And while his 128.0 passer rating is buoyed by some flukiness, he's undoubtedly run Kelly's offense with aplomb during the Eagles' three-game winning streak.
Vick, relishing his mentor role, is in the final year of his Eagles contract. While his own NFL future is in doubt, he sees bright prospects for Foles.
"He can potentially be a starter in this league for a long time. It's just about timing, as of right now," Vick said. "As long as he keeps doing what he's doing, he's going to continue to build that case."
