I am sorry Mike Miller is not worth 8-10 mil a year. If Danny won't give Tony Allen a 3rd year for 3 million dollars, I doubt he would give Mike Miller a contract of 5 yrs 40mill lol.
Mike Miller and Tony Allen aren't comparable. Tony Allen is excellent at one thing, but atrocious at things you kind of need your shooting guard to do, like hit a jumper and dribble the [dang] basketball.
Mike Miller could probably start for half the teams in the league and play 25-30MPG for every one of them. Tony Allen... not so much. Miller's an adequate defender (nowhere near as bad as his reputation), a good passer, one of the best rebounders in the league from the SG/SF position (comparable to Pierce at his peak), and one of the best shooters in the game.
He's had some injury issues, but a lot fewer than Tony Allen (and his game is much less sensitive to raw athleticism). Tonys younger, but his game won't age as well as Miller's.
Would Danny do a 5 year deal for Miller? Doubt it. Four years? Doubtful as well - but possible. We WILL need a shooting guard in two seasons, and Mike Miller should still be a very good player at that time.
