The Seahawks trajectory is so much steeper than the 49ers, San Francisco better get their ring this year, because the evidence suggests it may be the last time Caroll allows them a shot.
I don't see how this is relevant. PC inherited a team like most of you said needed a lot of work, and therefore needed to do more to improve it hence the steep trajectory the blogger points out.
On the other side, JH inherited a very talented team with all the pieces in place that was just missing a good coach to lead them. Why would Harb's fix what's not broken? Again, hence the steeper trajectory of PC as the blogger points out.
So far Harbaugh hasn't shown that he can rebuild a team because he hasn't been required to do so yet. Though his decision to make the questionable switch to Kaep early in the season is something that all the analysts (so called experts) have all eaten crow over and stated that that move alone speaks TONS about his ability to recognize talent and make the appropriate roster adjustments to make his team win.
The argument can also be made, that the blogger didn't point out, that Harbs has already demonstrated that he can lead his team to the Superbowl and even possibly win it, while PC hasn't yet. Yes Harbs inherited a great team, but that same team didn't even make it to the playoffs since 2002 until Harbs showed up and took them to the NFCCG his first year, and the Superbowl in his second year.
You don't go from a losing season one year to 13-3 and make it to the NFCCG the next year without a great coach.
I'm not taking anything away from the tremendous accomplishments that PC has achieved since taking over the Hawks, as I know that the Seahawks are definitely one of the better teams in the league now that PC is at the helm.
