Clearly, Chris Greisen got short shrifted in Arizona. There is no question about it.
Harry, I am surprised at your assessment of Greisen and the fact that you even question why the Cardinals used a 7th round draft pick on him. Greisen had a sensational career at NW Missouri St. Sure NW Missouri is not a Division 1 program, but the level of Greisen's play and leadership was outstanding. Didn't he lead NW Missouri St. to an NCAA championship?
How much of Greisen did you actually watch while he was a Cardinal? The happy feet you allude to applies more to Josh McCown than Greisen. Perhaps Greisen's greatest strength is his poise in the pocket. Two examples come to mind: (1) In a pre-season game a couple of years ago against San Diege, Gresien led a furious fourth quarter comeback. On the last possession that actually won the Cardinals the game, Greisen faced a 4th and 16. He took his five step drop and immediately there was a Charger linebacker in his face. Knowing he was going to get tattooed, Greisen stepped up and threw a twenty yard rope up the seam to Tywan Mitchell. The ball hit Mitchell's hands right in stride on the money. This stellar play kept the drive alive and led to the game winning touchdown. (2) In one of Greisen's only appearances in a regular season game, there was a similar situation...the rush was on him quickly but Greisen stood tall and delivered a perfect strike to Frank Sanders on a skinny post for a 20 yard TD.
I believe that Chris Greisen presented a real problem for Dave McGinnis. Greisen could attack the middle of the field in ways Jake Plummer never could. McGinnis had many occasions two years ago where he could have easily given Greisen a chance to play. For whatever reasons...we can speculate that Bill Bidwill issued a mandate to Mac that Jake take every possible snap...or that Mac was just hell-bent on not toying with Jake's confidence...for whatever reasons...Mac avoided using Gresien like the plague. And I believed this at the time and I still believe it, had Mac started Greisen in the Baltimore game late in the season three years ago...the year the Ravens won the Super Bowl...a game that the Cardinals clearly outplayed the Ravens...but, of course, a 4th quarter bonehead interception thrown by Jake Plummer sealed the win for Baltimore...had Mac started Greisen in that game, the Cardinals would have upset the Ravens that day and McGinnis would have had a full-fledged QB controversy on his hands.
The same reasons why Mac didn't play Greisen late in that season...a season in which Jake was pitiful...are the same reasons why McGinnis cut Greisen last year. Mac wanted no part of a QB controversy. By hanging on to two rookies instead, Mac built himself the perfect excuse to play Jake ad nauseum...which is exactly what Mac did...even at the expense of not giving his young QBs game experience when a myriad of perfect opportunities presented themselves.
Greisen was never given a decent chance to show what he could do. Don't tell me that a pre-season game against the Raiders was a decent chance. The Raiders dominated the hapless Cards in that contest in all areas of the game from start to finish.
I am not saying that Greisen is the next Johnny Unitas. But, Greisen has the intelligence, arm strength and poise to be a solid quarterback. You even contradict yourself, Harry, at the end of your post by saying you wouldn't be surprised to see Greisen land on another NFL roster...if so, why would you ever question using a 7th round pick on the guy?
To base Greisen's potential on his pre-season performances last year is a mistake.
